1) Consider the Protected LSD test, where we first use the F statistic to test the

alpha. If the global
You have to keep in mind that the LSD is concerned with familywise error
rate, which is the probability that you will make at least one
type I error in your set of conclusions. For the familywise error rate, 3
errors are no worse than 1.
Suppose that you have three groups. If the omnibus null is

There are a great many possible contrasts even with a relatively
small number of means. If you examine the data and then decide
what contrasts to do, then you have in some
