The hardest, or some would say easiest, question for the Test

What are Type 1 and Type 2 errors?

1 comment:

  1. Type 1 errors occur if you reject the null hypothesis when it is really true, and Type 2 errors occur if you accept the null hypothesis when it is really false. I feel like these are pretty explanatory answers, but often committed with business statisticians. It all comes down to how you state your hypothesis.
