3 experiments and the same 3 scales as DV - run Factorial Analysis together or sep

#1
Hi!

I realized three experiments (varying only the marketing context) and used as dependent variables the same three scales (attitude, purchase intention and experience). I carry out the exploratory factor analysis for each of the three experiments or perform only once for all experiments?

Thanks :):tup:

In the case of a principal component analysis (PCA) (which is highly related to an EFA -- as far as I know) you don't need independence of the data, which means that you can pool all your data and perform one single PCA. I guess it's the same for EFA.
