ANOVA terminology for a category of an explanatory variable. variability in scores that is primarily due to the different treatments that different groups receive. the impact of the explanatory variable on the dependent variable. a sum of the squared deviation scores representing all the variability in the scores. a sum of the squared deviation scores representing the variability within groups. ANOVA terminology for independent samples. a family of statistical tests for comparing the means of two or more groups. variability within a sample of cases, all of which have received the same treatment. |
