The act of partitioning, or splitting up, is the core idea of ANOVA. That’s what partitioning means, to split up. You can do this by adding new walls and making little rooms everywhere. What would happen if you partitioned the house? What would you be doing? One way to partition the house is to split it up into different rooms. Imagine you had a big empty house with no rooms in it. ![]() We already did some partitioning in the last chapter. ANOVAs are all about partitioning the sums of squares. Sometimes an obscure new name can be helpful for your understanding of what is going on. Time to introduce a new name for an idea you learned about last chapter, it’s called partitioning the sums of squares. Remember, that to use an ANOVA you need to have at least three conditions. That is, each participant is being measured at least three times. A repeated-measure ANOVA is appropriate to use when you have the same group of individuals in all of your conditions. In this chapter we will discuss repeated-measures ANOVAs. In the previous chapter we discussed independent-measures ANOVAs, which are appropriate to use when you have different groups of individuals in each of the conditions. ![]()
