For comparisons of more than two variables

â€¢

Ha always has to be that there is difference between one of the

three variables, not specific way

â€¢

Can't use confidence intervals or t tests to accurately compare

multiple population means

â€¢

Alternative hypothesis now just states that the population means are

not equal

â€¢

Testing the alternative hypothesis that they are not all the same to

disprove the null hypothesis that they are is the F test

â€¢

Analysis of variance F test usually carried out with a test statistic, P

value and computer software

â€¢

F test does not indicate which of the means are different, but just

that they are or not

â€¢
