REPEATED MEASURES (ANOVA)
RM ANOVA Page 3 The alternative univariate tests take into account violations of the sphericity assumption. These tests employ the same calculated F statistic as the standard univariate test, but its associated p value potentially differs. In determining the p value, an epsilon statistic is calculated based on the sample data to assess the degree that the sphericity

Understanding the One-way ANOVA
oak.ucc.nau.eduUNDERSTANDING THE ONE-WAY ANOVA The One-way Analysis of Variance (ANOVA) is a procedure for testing the hypothesis that K population means are equal, where K > 2. The One-way ANOVA compares the means of the samples or groups in order to make inferences about the population means. The One-way

With a one-way analysis of covariance, each individual or case must have scores on three variables: a factor or independent variable, a covariate, and a dependent variable. The factor divides individuals into two or more groups or levels, while

Design: Intercept+FathEduc The following is the MANOVA using the Wilk’s Lambda test. Using an alpha level of .05, we see that this test is significant, Wilk’s = .66, F(4, 142) = 8.12, p < .001, multivariate 2 = .19.
