In this part . . .
                                     Y    ou get all the nuts and bolts you need to understand


                                          one-way and two-way analyses of variance (also
                                     known as ANOVA), which compare the means of several
                                     populations at one time based on one or two different
                                     characteristics. You see how to read and understand
                                     ANOVA tables and computer output, and you get to go
                                     behind the scenes to understand the big ideas behind the
                                     formulas used in ANOVA. Finally, you see lots of different
                                     multiple comparison procedures to zoom in on which
                                     means are different. (Don’t sweat it. I always present
                                     formulas only on a need-to-know basis.)
