Document Summary

Need to know when it is appropriate to use an f test and post-hoc test and what tells you. Increase probability to find significant as we have more mean groups. Anova, is a test of multiple group means testing 3 or more groups/differences while holdings chance of type 1 error constant. Because they have the same approach between z and t. Looking at variance between group means and people within groups in order to tell differences in group means. Within group variance spread of distribution of groups (overwhelm aka overlap), easier to find significant. Between group variance difference in group means big f, big noise, small f less noise.
