How do you find the ss in statistics
WebWhen there are repeated measures for both factors, this value equals the number of subjects (3) minus 1, so df=2. Details on how the SS and DF are computed can be found in Maxwell and Delaney (reference below). Table … WebSS (Total) is the sum of squares between the n data points and the grand mean. As the name suggests, it quantifies the total variability in the observed data. We'll soon see that the total sum of squares, SS (Total), can be obtained by adding the between sum of squares, SS (Between), to the error sum of squares, SS (Error). That is:
