Question 5

Why did the single factor tests and analysis (such as t and single factor ANOVA tests on salary equality) not provide a complete answer to our salary equality question?

What outcomes in your life or work might benefit from a multiple regression examination rather than a simpler one variable test?

Solution

The single factor and analysis ANOVA explains whether the any significance difference among the groups (k-groups) but it does not tell about which group differs.

In this case we use pairwise comparission test.
