What type of analysis could we conduct to test this hypothesis?
A)Moderation
B)ANCOVA
C)Loglinear analysis

Mediation analysis can be used to test whether worry mediates the relationship between depression and sleep problems. It examines whether the relationship between an independent variable (depression) and a dependent variable (sleep problems) is explained by a third variable (worry) acting as a mediator. By analyzing the indirect effect of depression on sleep problems through worry, we can determine whether worry accounts for the relationship between these two variables.
