Question 7 Why can't a researcher just run multiple t tests when the independent variable has more than two levels? As you run more statistical tests, you lose degrees of freedom. As you run more statistical tests, it becomes harder and harder to reject the null hypothesis. As you run more statistical tests, the probability that you will make a Type III error in one of those tests increases. As you run more statistical tests, the probability that you will make a Type I error in one of the tests increases.
