We used a 2 (Expectation: teach/test) x 2 (Instructions: analogy/explicit) x 2 (Posttest: low-pressure/high-pressure) mixed-factor design, with repeated measures on the last factor. << Measures of effect sizes such as R2 and d are common for regressions and t-tests respectively. Then, after an equals sign, the actual value of the test statistic is reported to two decimal places. Partial eta squared is a way to measure the effect size of different variables in ANOVA models. Multivariate analysis of variance (MANOVA) is an extension of the univariate analysis of variance (ANOVA). This interaction resulted from the teach group showing greater accuracy than the test group exclusively when receiving analogy instructions. << /Event /View How to use Statas effect-size calculator. 24 0 obj All of which is to say, one should report parameter estimates along with statistical significance.
