Matrices Definition A rectangular arrangement of numbers (which may be real or complex numbers) in rows and columns, is called a matrix. Hence both Matrix A and Matrix B are equal. The assumption for the multivariate approach is that the vector of the dependent variables follow a multivariate normal distribution, and the variance-covariance matrices are equal across the cells formed by the between-subjects effects. 2) Equality of Covariance Matrices - p value should be non significant to accept the null hypothesis that the observed covariance matrices of the dependent variable are equal across groups. It multiplies matrices of any size up to 10x10. In the simplest case of a one-factor between-subjects ANOVA, dfn = a-1 dfd = N-a where "a" is the number of groups and "N" is the total number of subjects in the experiment. Step 1: Mention the values of two 2×2 matrices in the given input fields, Step 2: Click on “Solve” button to get the result. Let us have a look at how to use it. Matrix Calculator .
