Binary dv tests
WebThe first column highlighted, "R Square Change", shows the increase in variation explained by the addition of the interaction term (i.e., the change in R 2).You can see that the change in R 2 is reported as .068, which is a proportion.More usually, this measure is reported as a percentage so we can say that the change in R 2 is 6.8% (i.e., .068 x 100 = 6.8%), which … WebAug 22, 2024 · 1 You need to use the appropriate test for the data.
