WebTools. In statistics, a mixed-design analysis of variance model, also known as a split-plot ANOVA, is used to test for differences between two or more independent groups whilst subjecting participants to repeated measures. Thus, in a mixed-design ANOVA model, one factor (a fixed effects factor) is a between-subjects variable and the other (a ... WebDegrees of Freedom Formula: Let’s have a look at the following statistical tests and their related formulas for degrees of freedom calculation: 1-Sample t-Test: For this test, you can calculate dof by following the equation below: df = N – 1.
