I have a questionnaire survey and I have to use multivariate analysis to analyze the data.
where I have 22 question plus 4 representing a demographics information( like: gender, nationality, college..)
and I thing the best way to analyze this data is to use principal component analysis, but the problem that I'm confused by adding the demographics information or not, or I just need to use them after getting the result from principal component analysis??
please, if anyone have an idea about this or if anyone is a statistic teacher...please help me.
