Source: SS df MS F
Between treatments ___ ___ ___ ___
Within treatments ___ ___ 2
Total 132 ___
I've currently only gotten as far as calculating df as the following:
Between df: 3
Within df: 36
Total df: 39
But I can not for the life of me figure everything else out, what am I missing? Please explain to me how you came to your answers because I have the answer table, I just don't understand how to come to those answers. The answers are as follows:
Between SS: 60 | Between df: 3 | Between MS: 20
Within SS: 72 | Within df: 36 | Within MS: 2
Total SS: 132 | Within df: 39 | F-ratio: 10
Thank you in advance for your help!
