I am trying to perform cluster analysis on survey data where each respondent has answered several questions, some of which have categorical answers ("blue" "pink" "green" etc) and some of which have scale answers (rating from 1 to 10 etc).My problem is that certain age groups were over-sampled and I need to weight the data collected in order to accurately reflect the current population.Will it make a difference if I do the cluster analysis on the weighted data, and if so, how do I do cluster analysis on the weighted data?Any advice would be much appreciated!Thanks Emma
