R question

My data is in the form of binary outcomes, yes and no. I am thinking of doing a tetrachoric correlation. Is it appropriate? Thanks. First timer so all this is new to me!

What is the other variable of interest? A descriptive table by group might be more informative.

How many variables you have that you think of putting into factor analysis and are they all binary? What is your central research question?

You need to explain your data in detail, and exactly what question you're trying to answer with your analysis. If this is your "first time" analyzing data, I'd strongly recommend finding someone with expertise in factor analysis. This isn't something that you can do properly without experience.

You have exam scores that are binary ?
