I am working on a model, having one Independent variable, one dependent variable, one mediator, and one moderator. In order to reduce CMV, I want to collect data from Two different sources, i.e. data for the Independent variable is to be collected from the managers and the remaining variables are to be collected from subordinates.
I am confused about how to match the data collected from two different sources together?
and how to perform analysis for mediation and moderation?
like there will be lesser managers as compared to the subordinates, how to connect the two data?
