Question
Say I decide to do a 2 x 2 between subjects factorial design to examine how feedback on Facebook posts influence well-being. I am studying active (multiple posts a day) Facebook users.
There are two independent variables, each with two levels. IV A is Facebook "likes." For two days, participants will receive zero "likes" on all their Facebook posts or between 25-50 "likes" on all posts. IV B is Facebook comments. For two days, participants will receive no comments on all Facebook posts or between 5-10 comments on all Facebook posts. I will measure well-being before and after the study.
What can we learn from this 2 x 2 (Facebook "likes" x Facebook comments) factorial design, that we cannot learn from two separate experiments (one studying Facebook "likes" and the other studying Facebook comments)?
Explanation / Answer
One can learn the effect of interaction for independent variables-Facebook likes and Facebook comments, which is otherwise would not have been possible from two separate experiments.
