In the last chapter, we were able to compare two population means using either the large sample Z test or the two-sample t test. Analysis of variance (that is, analysis based on the variation in the data) often written as “ANOVA” concerns how to test the means of more than two populations.

The Analysis of Variance (ANOVA)
2010While the linear regression of Chapter 1 goes back to the nineteenth century, the Analysis of Variance of this chapter dates from the twentieth century, in applied work by Fisher motivated by agricultural problems (see §2.6). We begin this chapter with some necessary preliminaries, on the special distributions of Statistics needed for small-sample ...

Rietveld and van Hout (2005) provide this fictional example involving three second-language vocabulary learning methods (I, II, III), with three different groups of participants assigned to each method.1 The relative effectiveness of the learning methods is evaluated on some scale by scoring the increase in vocabulary after using the method.

In the last chapter we explained how it was possible to test whether two sample means were sufficiently different to allow us to conclude that the samples were probably drawn from populations with different population means. When more than two different groups or experimental conditions are involved we have to be careful how we test whether there might
