Beverage Consumption at Kalamazoo College

Kalamazoo- After nine weeks of researching, surveying, and analyzing data, the results concerning beverage consumption among college students are complete. The research was focused on the beverage consumption at Kalamazoo College. A finding likely to be interesting to the two beverage institutions on campus is the fact that among students and staff Biggby was frequented more often than Jazzman's was. It can not be said for certain that this was because Biggby's was rated higher than Jazzman's, but a few possible conclusions could be because of Biggby's location, or the name brand recognition. Among those students and staff that frequented Biggby, a larger percentage were female rather than male. This could be because males don't drink as much coffee as females or don't like Biggby's coffee as much as females do. Those that go to Biggby are most likely to be students or staff with high family incomes. This is possibly because of the high price of Biggby's drinks and there being a cheaper alternative (Jazzman's) not far from Biggby. One other finding that has relevance to the college, particularly to the company supplying the food in the cafeteria (Sodexo), is the fact that homemade coffee is preferred more than the coffee made in the cafeteria. Most likely it is because the coffee supplied in the cafeteria is thought to be lower in quality and taste than homemade coffee. Without getting too technical I thought I would give some numbers for the above conclusions in order to give the readers a more numerical context of the above claims. It was found that students and staff combined went to Biggby's one hundred twenty three times during the week and only 108 times to Jazzman's. Among those who frequented Biggby's 37 were female and 16 were male meaning that 70% were female and only 30% were male. On a scale of 1-5 the average rating for coffee made at home was 3.44 and the average rating for cafeteria coffee was 1.74. It is my hope that Sodexo will take into consideration these findings and consider improving the quality of their coffee.


Survey Leaves a Majority of Students Asking, “What is the K Plan?”

Kalamazoo College’s K Plan, known primarily as four essential aspects that embody the “K Experience” (the liberal arts curriculum, internships/externships, study abroad, and the Senior Individualized Project), seemingly have much more emphasis placed upon it during recruiting efforts than once students are actually paying money for it.

Our findings demonstrated that over half of K students cannot name two out of four parts of the plan, and 33% of students didn’t know what the K Plan was at all. This may be due to the fact that 71% of students surveyed had not discussed the K Plan with their adviser this year, which could explain the lack of awareness students have regarding it. Even if prospective students are constantly told about the K Plan they will soon forget it if it is never mentioned again.



However, when we examined the four parts of the K Plan individually, satisfaction seemed to be par for the course, as seen in the graph below, and the overall satisfaction with Kalamazoo College received an average score of 7.38 on a ranking scale of 1-10 - showing that while the college is not in trouble when it comes to student satisfaction, it definitely has room for improvement.



Delving further into the concept of the K Plan, we discovered that only between 31% and 54% of all sophomores, juniors, and seniors have participated in an internship or externship. While this statistic may seem impressive upon first inspection, we would like to remind readers that internships/externships are one of the major components of the K Plan and that it is interesting that maybe less than half of all students ever engage in one of the “corner stone” achievements Kalamazoo College is supposed to provide.

The K Plan does provide a comprehensive educational experience that surely benefits the students that comes to Kalamazoo College. However, if the college wishes to use this as a marketing tool, it would be in their interest to carry the image of the K Plan throughout the college experience in order for students to identify with the program that is, in one way or another, shaping their lives. The K Plan is as unique as the students it is guiding through college – it is up to the college to make sure it isn’t kicked to the wayside once that first check comes in.

Beverage Consumption Summary for the General Audience

Biggby’s v. Jazzman’s: Which one do you like more?

Our recent findings on beverage consumption from Biggby’s and Jazzman’s from Kalamazoo College included that more people go to Biggby’s opposed to Jazzman’s, and also people rated the quality of Biggby’s coffee higher than Jazzman’s. These conclusions were not very surprising due to the fact that Biggby’s is a franchise business that attracts more people opposed to Jazzman’s. Approximately 123 people went to Biggby’s compared to Jazzman’s where only approximately 108 people went to Jazzman’s. These numbers are out of our total sample of participants which is 133. The more people that went to Biggby’s displayed that Biggby’s ratings were higher than Jazzman’s when looking at all our data.

Also our findings included the fewer hours of sleep one gets the more cups of coffee one drinks. This is a reasonable finding due to the fact that coffee has caffeine in it and it helps people stay awake. It can be inferred the more cups of coffee one drinks the less amount of sleep one gets according to our data. This relates back to our earlier findings that people go to Biggby’s more for the better quality of coffee when they have less hours of sleep. In conclusion these are some of the findings from the survey amongst Kalamazoo College pertaining to beverage consumption from Biggby’s and Jazzman’s.

SIP Ideas

SIP #1
For a SIP using publicly available data, I would gather the statistics needed to enhance a restaurant including the theme, menu, and style of the establishment. I would collect statistics from other experimental methods studies about colors, fonts and themes that are most outstanding to the general eye, and types of foods that please the largest populations. I could test possible hypotheses such as which types of colors seem more attractive depending on gender, or whether or not people are more likely to enter a restaurant if it has a theme or not (i.e. a restaurant with strictly Italian food, Italian d├ęcor, menus with some words in Italian, etc. versus a restaurant without a specific categorization). Data would be available on the web at sites such as http://psycnet.apa.org/journals/cep/46/3/461/ or from sections of this book available on the web called Educational Psychology by William R. Reynolds and Gloria E. Miller.

SIP #2For a SIP using original data, I would use the same idea except would collect the data myself via surveys and studies of the customers/possible customers for the restaurant. The surveys would ask questions about colors, fonts, types of food, flavor combinations, etc. One question could ask about key ingredients, for example: “Would you be more likely to try a dish if it highlighted the ingredient A) ginger, B) basil, C) red pepper, or D) cinnamon?.” The same hypothesis tests listed above could be conducted and the sample would be the population within a 5-mile radius of the restaurant.

SIP Proposals

My first SIP proposal would be to develop a trading system using computer algorithms which trades a security based on s selection of simple trading tools. This list might include: 50-day MA, 200-day MA, a slow stochastic oscillator, MACD oscillator, Bollinger Bands, Volume, and basic trendline analysis. I would program a computer to look for these signals and that would buy or sell a security. I would use historical data from finance.yahoo.com or marketwatch.com. I could write my own backtesting software. I could use hypothesis testing to determine if my strategy returns higher than a market index with statistically significant results.

My SIP proposal which would require the collection of original data would be a cross-cultural study to determine how people from different countries view the importance of investing. I could do a stratified random sample from 3 or 4 different countries. I could measure things like percent of income invested, risk tolerance, or average expected retirement age.


SIP Proposals

Original Data - Where is Your Tuition Going?

My first SIP proposal, involving the collection of original data, is a comprehensive examination of the student perspective of tuition distribution, in regards to tuition breakdowns. This study would involve asking students where they think their tuition money is going towards, including room and board, athletics, facilities management, internet, faculty, etc. I would survey students at a high-price school, such as Kalamazoo College, as well as a low-price school, such as Western Michigan University. Also, it would be interesting to survey students from a large sports oriented school, such as the University of Michigan or Michigan State University. I would be able to test whether or not students believe more money to go towards faculty or athletics. As a conclusive test, I would research concrete tuition breakdowns from each university or college in order to put the students' guesses up against the actual layout. With such a grandiose of money being spent on both graduate and undergraduate programs in today's society, one should have the benefit of knowing exactly what their dollars are being for.

Publicly Available Data - What Makes the Tech King Tick?

This SIP proposal involves a study about the number one technology production company in the world: Apple. This company has started a revolution of technical innovation that has made its way to the top from the beginnings of the first Macintosh computer to the worldwide web surfing iPhone. I would delve into the very basics of Apple work culture, finding out what makes Apple work so well. I could research information on product history, price ranging techniques, office branching, and day-to-day life in the Apple workplace. An internship in the Apple headquarters in Vista Valley, California would be highly beneficial to this study.

The MBA SIP

Publicly Available Data- Is the Cost of a Top MBA Program Worth It?

Here I would be researching numbers based on business week’s MBA program rankings. Based on these rankings and other information, I would find relationships between program ranking and graduates’ average starting salary or cost of program in comparison to acceptance rate. Collecting data from business week and other sources including the school’s websites, there are many possible tests that could be performed. One possible hypothesis test would be to test that the average GMAT score for students entering a top ten program is higher than others. Here I would perform a one-tail test with H-naught being that the score for top ten and others are the same, the alternative being that scores for top ten schools are higher. Information about full-time MBA programs, as well as statistics for all programs, can be found at http://www.businessweek.com/bschools/rankings/ . It may also be helpful to consider other similar websites that provide rankings and other information (i.e. cost, graduation rate, average GPA, et.).

Original Data- Is the Cost of a Top MBA Program worth it to You?

For this I would try to send surveys to students at different universities. I would try to see how many business students plan on pursuing an MBA and what kind of jobs are they looking for in the future. I would also try to survey MBA graduates and rate their satisfactions in pursuing their MBA and if possible, compare their salaries with the cost of their MBA program. One hypothesis test could be to test the null hypothesis that students with hopes of becoming a CEO (or other high level position) are equally as likely to pursue an MBA as students with hopes of becoming something else, while the alternative hypothesis would state that students hoping to become a CEO are more likely to want to enter an MBA program. For this data I might use a sample of Michigan universities and attempt to get surveys to major universities such as Michigan, Michigan State, Western Michigan, etc.

SIP Proposals

A possible SIP topic could compare current health-care to the plan trying to be passed in Washington. This would take into consideration population and deal almost entirely with percentages of the demographic. This could include the current percent of the population covered, payment plans etc... AS a whole, the project could compare the two plans. What percent of the population currently owns health-care, how could the new plan expand percent covered?

http://www.kaiseredu.org/topics_im.asp?imID=1&parentID=61&id=358


A second SIP proposal incorporating the collection of original data, could concern the separation of the social-classes within the city of Kalamazoo. "Is there any one social class in particular prevalent in Kalamazoo?" A demographic could be drawn by compiling information through a census, either through the mail or door-to-door. The primary factor would be income (individual and collective), and concern percentages of Kalamazoo population.

SIP Proposal

One SIP idea that we could test using public data is to look at what sponsors on the PGA Tour win more. There is always a debate on who has the best product and which company to back if you want to win. Titleist, Taylor Made, Callaway and Nike are the big four companies when purchasing any golf equipment, who all advertise they are the best company on tour. We could look at who is sponsored, and look at every tournament in a given year, and see who wins and who they are sponsored by. If this was done over a period of a few years, it could be determined who is the most profitable and majority winner on the PGA Tour.

http://en.wikipedia.org/wiki/PGA_Tour



One original SIP idea could be if Grad school is important for Economics majors coming right out of college. It would be interesting to see, especially for me since this is my major and my dilemma, if students are more successful getting jobs if they attend grad school or not after their 4 year college term. You would have to get a list of schools and their Econ majors and follow them post-collegiate years to see what kind of jobs they get, how long it took them to get that job and possibly how much money they make annually.

SIP ideas

1st SIP: Presidential Approval

A SIP idea that one could perform would be to examine the differences in presidential approval rates throughout the last couple of years based on Gallup Poll research. One could look at specific periods of time where the approval rating drops, to where it raises, and then look at other variables such as bill proposed or vetoed by the president, congressmen or others speaking out against the president, presidential action overseas, and other different aspects. This could be an interesting topic to look at especially in these times when the country is divided in approval, and to look at what other presidents have to done to improve their rating to watch for current and up and coming presidents making similar decisions or actions.

http://www.gallup.com/poll/124922/Presidential-Approval-Center.aspx

2nd SIP: The Cost of Entry-Level College Courses

One SIP idea would be to measure different levels of education from surrounding colleges/universities. I could communicate with colleges/universities and research entry-level courses in economics. Schools like Michigan, Michigan State, Western, and Kalamazoo Community College, to see what differences there are in the types of education offered. If possible, I could speak with the head of each department from each school and ask them to distribute a survey asking details about what the course contained, and then a final exam from one of entry-level courses here. The objective of this would be to see if the entry-level courses here are worth the extraordinary difference in price. A null hypothesis one could test is whether there is no difference in the education offered at Kalamazoo College and Michigan State. It would be interesting to see if there is a significant difference in the education level, or what information is being taught.

1. SIP using publicly available data.
I would like to investigate the ways in which people receive/locate information. There are very many media outlets available to us at the present, and I would like to see how increases in use of one would effect the use of others. Also I would like to investigate how those outlets are used. How much of the information gleaned from internet use is useless nonsense compared to the information received from books, the radio, magazines, and others. Has the amount of useful information that people are presented with daily declined since the invention of the internet? Has the amount of advertising people are subjected to increased, and by what factor? My sample for the original data proposal could be a cluster/neighborhood door to door sample. First I thought of college students, but I assume that using them would result in extreme bias seeing as many spend all hours of the night on facebook.
http://www.rba.co.uk/sources/stats.htm (magazine subscription stats)

2. SIP using original data.
I would really like to undertake a SIP concerning the populations knowledge and level of caring about environmental concerns. I think many of the most dangerous environmental problems are generally unknown to the vast majority of the public. I would like to investigate across all demographics in order to include the entire population, thought unfortunately it probably wouldn't be time/cost effective to find a sample that embodied the U.S. or world populations, I could probably do all of Michigan. I think surveys and behavioral observation would be the ideal data gathering techniques for a project like this. Possible hypotheses include 1. Level of education (regardless of type) has a positive influence on both knowledge and caring. 2. Women are more likely to be concerned.

Potential SIP Proposals

One potential SIP study would be to examine the factors that go into voter turnout of presidential elections. An initial regression could be set up with voter turnout being a factor of exit poll results regarding major issues, overall campaign spending, number of voting age populace registered to vote and voting age populace demographics (age, race, income, gender etc). Within these categories, there are a number of interesting hypothesis tests that could be done. For instance, one could ask if there is a significant increase in voter turnout when greater amounts of money is spent campaigning; if having the economy be the top issue in exit polls drives more people to the polls than national security; and if there is a statistically significant difference between the proportion of college age students that turned out to vote in the 2008 election as opposed to other years.

Here are some sites that could prove useful:

The American Presidency Project: http://www.presidency.ucsb.edu/data/turnout.php
The Roper Center's U.S. Election page: http://www.ropercenter.uconn.edu/elections/presidential/presidential_election.html
U.S. Census Bureau: http://www.census.gov
Pew Center Election Turnout: http://www.pewcenteronthestates.org/ttw/trends_map_data_table.aspx?trendID=19

A possible international spin on this idea would be to find these same data sets for another industrialized nation such as Great Britain or France, and see how the information compares.


My second proposal looks at the effect of the Kalamazoo Promise on teachers and curriculum in middle and high school in comparison to other school districts in communities with similar demographics. Although the Promise has been in effect for a number of years now, there is still relatively little knowledge about its effects. Of the information available, much attention is paid to its effects on students. However, it seems as though little research has been done to see how a program such as the Promise might affect teachers. Therefore, this proposal provides the chance to make original findings that have relevance both locally and nationally.

Methodologically, a stratified random sample of teachers in Kalamazoo Public Schools at the middle and high school levels would be administered a survey that would cover a range of issues including, but not limited to, the extent to which teachers talk about college with their students, personal fulfillment with regards to occupation, number of hours spent preparing outside of the classroom, amount of interaction with parents, and amount of classroom time spent doing college prep. This same survey would then be randomly administered in two or three other school districts within cities with demographics fairly similar to Kalamazoo. A range of hypothesis tests could then be done to see if the Kalamazoo Promise substantially increases the results for teachers in KPS with regards to each of these questions. One could also see if those changes are more likely to occur within groups of teachers that teach certain subjects or have taught for a certain number of years.
One SIP idea using publicly-available data could be to research what affects go into a NBA career compared to a WNBA career. The affects i'm thinking of include: Marriages, salary, pregnancies, injuries, etc. I would try to gather information via the NBA and WNBA by website or by phone. The one big hypothesis i would like to test would be that the WNBA players have significantly shorter careers than WNBA players because of the many factors mentioned above.

www.wnba.com


Another SIP idea using original collected data would be to do an internship with a big company and survey their employees asking about their happiness and other factors within the company itself. I would test for the hypothesis that an employees happiness is based upon certain factors that would be collected from the survey.

SIP PROPOSAL

My first SIP topic, using publicly-available data, would be taking a look at the highest paid professional sports teams, and comparing whether higher paid teams have better results in their respective sports. The New York Yankees recently won the World Series last year, and it so happens that they are the highest paid team in all of professional sports. But then, you have a team like the Dallas Mavericks, who are the fifth highest paid team in professional sports, who have yet to win a championship. So the methodology I would use is watch and follow one of the highest paid professional sports teams during their season, and maybe try and get an internship or set up an interview with the owner or general manager of a professional sports team, and ask them what goes into making a good team, and if they believe paying higher salaries improves performance, and gets star athletes to come to your team to try and win championships. I don't believe this would be that difficult, because just 2-3 hours away are the Detroit Tigers, who are one of the highest paid Major League Baseball teams. So overall, the hypotheses I would test is if higher paid professional sports teams, over the years, have had more success in their respective sports than that of lower paid professional sports teams, and if professional athletes that get high paying contracts, are more likely to play as good than when they had lower salaries earlier in their career. I would find the solution to this simply by looking at their statistics over the years they were paid lower, and the years were they were paid higher, and compare the two to see if there was an increase in the majority of their production statistics , or a decrease in the majority of their production statistics.
Another SIP topic to collect original data would be to survey a sample of students (methodology) here at Kalamazoo College on whether they think a new, bigger weight room should be built for the college. I would draw up questions such as: how often do you work out? do you work out? should Kalamazoo College spend millions on a new weight room? The hypotheses I would test seeing whether students who work out would more so rather have a weight room than students who don't work out, and whether more male students wanted a new weight room than female students, and if the majority of the sample I took of students would want a new weight room, all factors included.

Sip Ideas

One topic using publicly available data would be to measure the effects of the EURO on the EU countries economies. This study would allow us to see whether or not the EURO has had a positive on all of the countries economies or if there is a varying amount of benefit for France and Germany while countries like Greece suffer. We can look at historical data of their growth rates and how they changed over time. and how their GDP has been affected comparative to other countries in the EU. There is a site that could aid in this: http://www.ecb.int/stats/html/index.en.html Possible hypothesis tests would be something along the lines of, do each countries get the same benefit. Ho they do. Ha they do not. They are doing relativly worse now then they were before. Ho: they're doing the same. Ha they are doing worse.

A study that could be collected would be one examining the effects of private college education on getting into higher end graduate schools. You would need to new admittance into high end grad schools. (Schools ranked in the top 50 grad schools) and check which colleges they came from, what their GPA was and scores to get in. You could compare the difference between the public school scores needed and the private school scores needed to get in.

SIP Idea

One SIP study that would have publicly-available data could be to assess the internation trade and tariff profiles. The statistics would be provided by the WTO and the World Bank. A good topic to study would be how free trade affects countries or something along the same lines. The methodology in gathering data would be to compare nations who are members of the WTO, i.e. those nations which comply with the WTO trading regulations to countries that are not members of the WTO. Of course those nations within the WTO are called free trade nations, however this can be taken with a pinch of salt as there are a lot of policies which continue to make free multilateral trading difficult. an example of this would be government subsidizing their domestic companies. Hypothesis testing can be carried out by comparing the data collected yearly or to see if there is significant differences in trading between economically developed nations and less economically developed nations.

Another possible study would be to see how a typical household is affected by the new national health insurance in Kalamazoo. The study would mainly measure the differences in spending on medication before and after the health bill has come into affect. This would be interesting as one could see the trends in pharmaceutical consumption. To obtain the data, I would perform a sample survey in each of the Kalamazoo neighborhoods at random, perhaps 10 household in each neighborhood. To see if there are statistically significant data I could hypothesis test by comparing the amounts spent on medication before the health care bill was passed and the amount spent after. Another hypothesis test could be to compare each of the neighborhoods as there would be a difference in income .

sip proposal

One SIP topic for using publicly-available data that would interest me would be Ferrari productions. Due to its low production volumes and its famous name, it can do nearly anything technologically that it is inclined to do, making it very expensive. It is also limited. It recently announced its commitment to building future production vehicles like the engine, transmissions, pedal assemblies, steering gear, suspension pieces, body panels out of aluminum. The methodology I might use to study it would be trying to get an internship at Ferrari and be able to be in the manufacturing process and research on where they get the supplies and how much money is used to build these cars. I would also like to know how many Ferrari cars were only produced at a certain period of time. Some possible hypothesis to test would be gas and average income, company’s income and salary, and export and car buyers.

http://www.ferrarichat.com/forum/showthread.php?t=196388

http://www.edmunds.com/ferrari/index.html

Another SIP topic to collect original data would be finding about alcohol prices. Many different stores will have different prices of alcohol. Some people might not care about the price and might go to the closest store. Others might care about the prices and might need to drive a bit further to save money. The methodology I would use to study it would be something in my neighborhood. I would find out how many miles apart are stores that sell liquor from my neighborhood and go to each store and write down the prices of certain alcohol. I would then type up a survey and go to door to door asking to take the survey. In my survey I would write only a list of specific alcohol and ask them which store they would go to get these items. It will help this study by figuring out if the people who took the survey actually care about the prices or not of alcohol. Some possible hypothesis to test would be gas and income, alcohol price and income, liquor stores and big stores(Meijer, Costco…) , consumer spending and store income.

SIP

For a potential SIP using publicly available data I thought that comparing state by state High School rankings created by Newsweek and demographics gathered by the Census Bureau could provide an interesting insight to our nationwide education system. I would collect financial data (mean family income) of the top 100 high school districts and test to truly see how big of a role money plays in education. I could dive even deeper and test the longevity of the high school's prominence and potentially tie it to some long term economic dependence with in the region.

For a SIP using original data, I could set up a comparative education satisfaction test. I would randomly survey about 300 seniors from 3 private colleges in Michigan and 300 students from 3 public universities in Michigan. My goal would be to find out if, overall, public or private educated seniors are more satisfied with the education and college experience they received. In other words, is that extra 20 grand or so a year worth the investment for a private school education?

(Possible) SIP Proposals

One possible SIP topic using publicly-available data could be analyzing the evolution of the health care debates that have transpired (which is not to say that such debates are even close to being fully finished). While this SIP would obviously deal more than with simple statistics, such data would prove essential to any argument that would be made. In order to study such findings, one would compile a large number of surveys measuring public opinion of health care or other such factors of certain aspects of health care reform (i.e., the approval of a public option). Then one could analyze these results over time and measure whether there were statistically significant findings with regard to approval over time. In addition, further hypothesis tests could be done to see which demographic groups most strongly supported/opposed health care reform and its various aspects (such as the rich/poor divide or gaps between races).
Furthermore, additional data could be looked into such as if there is any correlation between support for health care reform and general trust in the ability of Congress to pass legislation. Data could also be used to analyze the voting patterns of congressional members by viewing the proportions who voted in line with their political party or whether an impending election (2010) may have had any influence on voting patterns.
Such analysis may then possibly lead to a conclusion as to whether Democrats could have simply strong-armed a health reform bill through congress that included a public option rather than the admittedly watered down “negotiation” bill that has passed. Of course, numbers cannot fully tell the whole story but it would offer great insight to the power of the minority that is now found in the legislature.

These data are easily found on the internet through various means:

Blogs: http://www.fivethirtyeight.com/search/label/health%20care
News Sites: http://topics.nytimes.com/top/news/health/diseasesconditionsandhealthtopics/health_insurance_and_managed_care/health_care_reform/index.html

Another SIP topic would be one where one would collect original data in order to measure the effectiveness of Woodward tutoring programs (including both the after-school PALS program and regular in-class tutors). By partnering with the school, one may be able to obtain data from standardized testing and be able to compare the scores of students who have had no contact with tutors, contact with either in-class tutors or a PALS tutor, or a mixture of both. One would then be able to test a hypothesis test in which one could measure the level of significance to which the tutoring programs have assisted (presumably) in raising students’ scores. With large enough findings, it may allow the programs to receive more money so that they are better equipped to help assist such an underprivileged school demographic. Furthermore, tests could measure the differences seen between boys and girls, income, etc. in order to analyze further socioeconomic factors that a simple test of tutor/no-tutor would leave unexplained.
Ideally, the sample size would be able to be the whole Woodward Elementary student population since obtaining all the data as opposed to just some of it should be a negligible increase in difficulty.

SIP Proposals

First Proposal:

My first proposal for a SIP project is to use public statistics to examine the relationship between poverty levels and race. I would use data on whites, blacks, Hispanics, Asians and the poverty levels of the groups. For this SIP an example of a null hypothesis is that percent of people who live below the poverty level of blacks and whites are the same, therefore the difference between the two is zero. An alternative hypothesis is that the percent of blacks who live below the poverty line is greater than zero and so the difference between the percent of blacks who live below poverty and the percent of whites is greater than zero. These hypotheses could be repeated using different races because the census provides that information.

http://www.census.gov/hhes/www/poverty/histpov/hstpov2.html

Second Proposal:

My second proposal for a SIP project is to study the percent of blacks in Kalamazoo who live below the poverty line and the percent of whites. I would sample residents of Kalamazoo by doing cluster samples of different blocks within the city to gather original data. Similar to the first proposal, I would have a null hypothesis that two (e.g. Asians and Hispanics) rates of people who live below the poverty line are equal. My alternative hypothesis could be that Hispanics have a higher percentage poverty rate than Asians and so the difference would be greater than zero.

sip proposals

If i were to conduct a sip idea using public data in order to collect original data I would use the US census site. I would conduct a survey viewing the better places to live in America bases off several different variables. I would randomly select states from each region of the united states in order to ensure i have a variety of states with different weather and circumstances. Then i would compare family incomes per state then adding in the variable of average temperature per year and also the number of the population in each state may be variables affecting income. I could do hypothesis testing with income through simple one tailed tests comparing souther states to northern states income. Then i could compare income of states with their average temperature or population size through hypothesis testing.

-Census.gov

For an original data sip idea, I would target the expenditures made by college students who use their own money or their parents money to pay for things such as clothes, food, alcohol, gas, coffee, etc. After randomly selecting students to participate in this survey, i would ask them for their demographic information including income and gender. Hypothesis testing would include do men or women pay more for these expenditures on their own, do higher incomes mean more parents pay for their kids, do higher income students buy more alcohol than students with lower incomes, etc.

Possible SIP Topics

For a SIP with publicly available data, one suggestion is to look at college tuition rates across the country. I would look at schools and compare different tuition rates based on their location, size, division I II or III, private or public, etc. I would use collegeboard.com to find this information. I would then try to randomly pick regions throughout the United States and look at a certain number of colleges in each area. Next I would explore some hypotheses such as: private schools are x amount more expensive than public schools, or a certain region is more expensive than another region.

For a SIP with original data I would use the topic of alcohol. I would ask students how much money they spend on alcohol in a given week, if they are a male or female, how much they study per week, what their GPA is, what their family income is, if they have a job or not, etc. Some possible hypotheses to test would be: Men spend more money on alcohol than women, those who study more spend less money on alcohol, students who have a job spend x amount more on alcohol than students who don’t have a job. A possible sample would just be randomly selected students here on campus.

SIP Proposals

For my SIP using publicly available data would analyze the increase in the autism rate over the past three decades. In the 1980's autism affected about 1 in every 10,000 children. By the late 1990's this number has increased to 1 in every 166 children. Now this number is estimated to be every 1 in 110 children. Some reasons for this increase are environmental effects increasing, and more things are being considered autistic. To study this I could compare the raw data to reported data by organizations, and hypothesis test how autism affects different races differently. Some data on autism could be found at autism society of america.
For a SIP where I could collect data on my own I would analyze the family income of incoming freshman. To study this I could encourage the college to add this to some required form, and keep the results anonymous. I could also survey incoming freshman myself while also keeping the results anonymous. A possible hypothesis is to compare the GPA of freshman to their family income. A possible sample for the survey would be to systematically select every 8th freshman in alphabetical order.

Potential SIPs

Both of my Potential SIPs are pertaining to automobiles:

From Kelly Blue Books, www.KBB.com, I would be able to research vehicles and all the statistical data about them including MSRP, Miles per gallon, horsepower, weight, etc. Using this data I could hypothesis test how much horsepower would expect to have a certain amount of miles to the gallon, using the weight and horsepower, I would be able to hypothesize how well certain cars would do on some performance tests such as 0-60, quarter mile, skid pad, slalom, etc.

If I were to conduct my own statistical research, I would randomly survey about 100-200 people asking questions about the cars they own including year, company, car, trim level, the miles per gallon they would expect their car to get, any aftermarket modifications, any tickets they had received, whether or not they use radar detectors, and obviously demographic questions. From this data, I would be able to find what types of vehicles (SUV, Sedan, Coupe, etc.) consumers in the specified survey area invest the majority of their money into, as well as how much they invest in keeping their vehicles "up to date" with modifications.

SIP Proposals

My first proposal for a SIP project is based upon the use of already available public data. The data would be gathered from statistical information taken by the U.S. Census Bureau during the 2000 Census. The topic would be about education in the United States. It would be conducted by figuring out the number of people who had high school diplomas in each of the 50 states. This could be done by dividing the percentage by the total population and then subtracting that amount from the total population. In addition to gathering the information about the number of people with high school diplomas, the number of people with bachelor degrees and higher for each state would be found. Once this data was calculated it would then be possible to run hypothesis tests. Some possible tests would include comparing the number of graduates in each state, or by grouping states into regions and comparing regions. These tests could also be run for bachelor degrees and higher.

My second proposal for a SIP project involves the person conducting the study to gather their own original data. The topic would be about smoking and college students. The data would be gathered by creating a random sample and then surveying that sample. The survey would include questions such as age, race, family income, state of residence, personal income, hours of sleep, working(y or n), GPA, future plans i.e. grad school etc., year in college,athlete (y or n),smoke (y or n) if a smoker how many packs do you smoke a day, what brand, reason for smoking, date started smoking, want to quit (y or n). Hypothesis tests that could be run include do smokers have a lower or higher GPA, Do smokers have a lower family/personal income, does one state have a higher percentage of smokers, does a particular race smoke more than another, are there less athletes who smoke, do more people want to keep smoking or quit. A sample of students could be obtained either from Kalamazoo college, Western Michigan University, or a combination of the two.

SIP Proposal

Proposed SIP Topics

My first proposed SIP topic is using the public data. The public data that I would obtain is the amount of arrests amongst juveniles in the different counties in Michigan. These arrests would include how many times juveniles were arrested and the amount of times for certain types of crimes that took place for an arrest. The methodology I would use to study this data would be to divide the information by counties and compare the counties to another based on the data provided. I would compare the amount of juveniles arrested and the number of juveniles arrested for a particular crime. Some hypothesis tests that I could run are comparing two counties with the amount of arrests to determine which county actually had more arrests. Also I could run hypothesis testing on the number for each specific crime. This concludes my first proposed SIP topic.

My next proposed SIP topic would also be pertaining to juveniles. I would focus on the Kalamazoo Juvenile Home and the inmates would make up my sample. I would randomly survey the inmates and ask them questions about their level of crimes, their retention rate, the different types of crimes they have committed, the duration of their stay in the Juvenile Home and also questions pertaining to demographics. A possible hypothesis test that I would run is comparing the percentage of boys versus girls in the juvenile home and determining if actually there are more boys than girls in the juvenile home. Another hypothesis test that I would consider running is if the average retention rate amongst juveniles is that high compared to the US average. This concludes my second proposed SIP topic.
