I have different parameters, i.e. Shoot length, root length, F/D biomass, etc. Similarly, I have 18 varieties and each variety has 3 groups (Control group, Treatment 1, Treatment 2), each group contains 15 replicates. I want to s screen out some varieties. I don't know how to set this data in excel for PCA analysis. Here is a file in the attachment which gives the complete information. Please, guide me on how to set this data for PCA analysis?
