I want to do some basic analysis and run various scenarios - if we filter out all persons who respond X, Y, Z and A, B, C - what does the remaining group look like (measured by a response in the instrument (a self rating the respondents have did)). I’d like to set up the base so that I can adjust the criteria - the filter - and see how this effects the remaining pool.
