I don't know how to analysis my data. My statistical model is factorial in CRD, factor is 2 diets and 4 breeds. I would like to analyze marbling score. should i analyze by FRIEDMAN test or another? And how to know different between 2 of factor and interaction? 

if you give me an example or SAS code, i will be too much appreciate.

1	1	4
1	1	1
1	2	1
1	2	2
