Web38.1 What does MANOVA test? Exactly what is that null hypothesis? Like ANOVA, MANOVA experiments involve groups of factorial predictor variables (it is possible to run MANOVA on only two groups). The null hypothesis addresses whether there are any differences between groups of means. As in ANOVA, this is accomplished by partitioning … WebThe first null hypothesis tested in a multivariate analysis is that when all the covariates are controlled, there is no correlation between any independent variable and any dependent variable. Thus the tested hypothesis refers to all the correlations in an asymmetric p x q matrix of correlations. These will be partial correlations if there are ...
