Multivariate Analysis

I am required to use an analysis method to analyze the data we got from the questionnaire. This is a Marketing Analytics class and my group is doing market research on ZARA, we came up with a questionnaire and we need to describe what multivariate analysis technique we propose in order to analyze the data we got and how these would help the client’s research aims. (You are not required to actually conduct analysis). We chose the regression technique, so you have to use it. I will attach some documents you may find useful. Just explain, you don’t need to actually do any calculations, just do explain well.
