1. Explain the difference between a mediating variable and a moderating variable. It may be helpful for you to draw a picture as it relates to this study as a part of your response.What are the assumptions of ordinary least squares regression (also called multiple regression)? Please define each of them. If these are violated, what can you do (in addition to using another method of analysis) to fix these problems?Is it appropriate to present the means for dichotomous variables instead of counts and percentages as seen in Table 1? Why or why not?The way that the results in this study are presented is incomplete. If you were asked to edit the article and redo the results in Table 2, what other data would you need to have included in this table (per APA 7th edition)? Why would it be important to include this other data and not just the coefficient, standard errors, and constant?
