Would someone be able to help me out with my masters degree statistics/data analysis questions? I have my conceptual model and hypothesis done and now my mentor said "do a principal components analysis, then cronbach alfas and then multiple regression for some hypothesis I only need to do a simple linear regression, which I kind of understand. But I never had data analysis before and I am not really sure especially what a principal components analysis is for and even when reading about it I quite can't understand how I am supposed to read the informations and what kind of conclusions to take out of it.

​

I could send my conceptual model and hypothesis if someone is down to help me out with it!

​

Thank you
