Which experimental design is this? Factorial vs within groups?

Question

I have two independent variables (age and gender) and one dependent variable (the results of a questionnaire using a Likert scale). I'm trying to see whether age and/or gender have an effect on the results of the questionnaire. All participants answered the same questionnaire. Is this a mixed factorial design or a within groups design?

Answer 1

I would say this is a correlational research design because you are not controlling age and gender. Therefore, you would use a multiple regression analysis to determine if age and/or gender predict scores on your DV.

In a true experiment, you would be manipulating the IVs.
