Discuss the differences between a between subjects factorial design, a within-subjects factorial design, and a mixed factorial design.

Provide an example of how a factorial design could be used to answer a research question in Educational Psychology, including an identification of the type of design it would be (that is, 2×2 between subjects, 3×4 within subjects, 2×3 mixed factorial). 

Make sure to identify the independent and dependent variables and their scales of measurement.
