Family-wise error rate

The likelihood of finding a Type I error increases with the number of tests being run. The significance level and number of tests being run can be used to determine the Family-wise error rate, or the likelihood of obtaining one or more false positives, or Type I errors, when running multiple tests.

Derive the Family-wise error rate for a small and large number of tests, noting the increase in likelihood of a false positive being found among the group of tests.
