Document Summary
6 (sampling distribution of differences in means, t-test, anova) ch. F distribution eta-squared proportion of variance explained (pve) one-tailed test two-tailed test t-test critical values. Anova degrees of freedom between-categories variance within-categories variance total variance. Problem with difference of means: interpreting it is easy, but you can"t tell if it"s big/little/ or in the middle for effect size. Pve measure: pve = proportion of variation explained. How much variation in the dv is being explained by the iv. Ie, think of it as covariance: recall overlapping circles, pve varies from . 0 to 1. 0, less than . 02. 3: two advantages , exact measure of how important the relationship is, compare it with other measures: In male predominant cities, about 3. 5 more residents per thousand are receiving ei. Can treat as no relationship weak moderate strong. In options: click for anova table and eta : continue, ok, this opens your output window with four tables, first is case processing summary .
