To produce the Analysis of Variance (ANOVA) table set choose Statistics Analysis of Variance. An analysis of variance table is meaningful only when the column variable is a number field and the row variable is a multiple choice type field in crosstabulation.
Analysis of Variance tests for the null hypothesis that all the categories have the same average value for the column variable. If at least two categories are not the same, the hypothesis will be rejected. This test is based on the assumption that all categories have the same variance.
