Hello everyone, sorry i am a noob here so i need help

I wanted to a mediation analysis between some variables i got from my survey.

The question is, how can i group the variables for it?

meaning.... for example some of the variables can represent (The Environmental factors) and some of the variables represent (Personal Factors) and some are (group factors). so i want to group each set of variable together to do the mediation analysis.

Hope i was somewhat clear , sorry i am not good at this so any help or Tutorial link will be appreciated


Also, i am not sure if i am posting this on the right forum, i am not familiar with this site so i apologize in advance.
