I'm confused about how to arrange data for PCA & factor analysis. I want to see the association between physico-chemical variables and infection parameters of fish. In addition, I want to correlate with other features of fish.
Dear sir,
You need grouping variable and independent variables for PCA and DFA analysis in SPSS. If you have 2 populations/species take grouping variable as name of the population/species then put the corresponding independent variables against the grouping variable. For example...for two populations..

For variables given above you can use your parameters like DO, Alkalinity, or Organism length, height etc...
I hope this could enlighten you to some extent.
