Document Summary
Chapter 11: factor analysis of variance f. a. Two main effects: one for comparing boys/girls and another for children of different regions, one per iv and each has own f-value. Interaction effect: present when the differences between the groups of one. Iv on the dv vary according to the level of a 2nd iv (aka moderator effects: homogeneity of variance: amount of variance within each group if roughly equal. Dv while controlling/partialling out the effects of the other iv(s) on the dv: test whether any statistical interactions present and level increases as # of ivs increase c. Effect size: sources of variation different ways that the variance of the dv is partitioned by the. 0. 05 and thus the overall model is statistically significant. 2: eta-squared can be interpreted as practical significance or the combined effect size whose value is not affected by sample size (maybe a better indicator)
