Pic related. I really need help with which statistical method to use for analyzing data for the following:

>24 Subjects are given a survey where they will run into 3 possible, random scenarios (1, 2, or 3).
>For every scenario a subject encounters (1, 2, or 3), they must then answer 3 questions (Factor x, Factor y, and Factor z).
>Each Factor has a Likert scale using a 1 - 7 rating system.

The subjects will be doing this for 100+ times. I am interested in finding out what which scenarios produce the highest mean scores for every factor.

**Also**
>If I was comparing this information with 2 groups of 24 instead of one, what statistical method would I use If I wanted to see who had the lower overall factor scores for each scenario?
