Hello! I need your help since it's the first time I use SPSS. The aim of my study is to explore the impact of economic crisis on the airport workplace. I want to test if there are statistical differences between airport with different ownership, size, etc. I have collected 89 employees responses from 40 airports and I have created an SPSS data file. That means that I have multiple responses for the same airport in many cases. My question is: can I do all my statistics with the 89 responses or do I have to group all the responses coming from the same airports so as to create a sample of N=40 (airports)?
In that case, how I group the responses?
Thank you very much,
