Dr. Leilana is investigating the relationship between joining a book club (book club status) and # of books read. More specifically, Dr. Leilana thinks that joining a book club leads to a greater appreciation for books, which leads to a greater # of books read. What is one way Dr. Leilana could assess if book appreciation is mediating the relationship between book club status and # of books?
O Look at the strength of the correlation between book club status and # of books when she is controlling for book appreciation compared to when she is not.
O Check to see if there is a bivariate correlation between book appreciation and # of books.
O Conduct a longitudinal study and look at the cross-log correlation between book appreciation at time 1 and # of books read at time 2.
O Assess if the correlation between book club status and # of books is stronger for people with high book appreciation compared to low book appreciation.
