Mediation and Moderation

For Week 11, I would like you to apply your knowledge of multivariate correlational studies. Please follow the instructions below carefully and answer all parts of the instructions.

Discussion Post Instructions: In one post, include the following information:

1) Choose two psychological variables whose bivariate relationship is of interest to you. These should be psychological in nature and not just any two variables.

For example, you may be interested in the relationship between intelligence and general life satisfaction. These would both be psychological variables because they measure the mind and/or behavior.

2) Give an example of a potential mediating variable that explains why the bivariate relationship exists between your two variables. Clearly explain your response to demonstrate your understanding of mediation.

For example, I may hypothesize that the mediator between intelligence and general life satisfaction is higher income. Individuals with higher intelligence get higher paying jobs and that higher income then leads to higher general life satisfaction.

3) Give an example of a potential moderating variable that explains for whom the bivariate relationship exists. Clearly explain your response to demonstrate your understanding of moderation.

For example, I may hypothesize that the relationship between intelligence and general life satisfaction is moderated by biological sex. Perhaps the correlation coefficient between intelligence and general life satisfaction is large, positive, and significant for females but zero and not significant for males. In other words, the relationship between intelligence and general life satisfaction is moderated by biological sex.
