Hi everyone I am a masters student and I am currently cleaning my dataset and running tests. I want to be able to run multiple regression tests to do a mediation analysis, correlations, etc. and I need to create indexes. I was successful in creating two indexes each measuring attitudes on a 0 to 100 scale. However, I am having trouble creating indexes that are also measured on a 0 to 100 scale but they are based on a previous question that had respondents select multiple options (at least 3) which then those selected options popped up for the next few questions. Example: respondents chose which 3 podcasters from the list they listen to most often. Then the ones they chose appeared to which they measured how frequent they watch, how engaged they are when watching, etc. all on 0 to 100 scales.
I’ve tried computing these into indexes by the mean function mean.3(podfrequency1, podfrequency 2, etc.) but I think something is going wrong. When I run a frequency after my N decreases significantly. Also, when I try to do a reliability analysis with all the variables it can’t produce because it says N=0.
What am I doing wrong? Is the index even possible? Thank you so much!!!!
