Analysis of variance is the most common inferential statistical procedure used to analyze experiments because
 
  a. it is the only statistical procedure that can test either between-subjects factors or within-subjects factors.
  b. there are several different versions of it, and so it can test for possible treatment effects more accurately than the two-sample tests.
