Scenario: You pick up a newspaper and read the headline: “Higher income is linked to greater marital satisfaction!” You tell your friend about the study you read and she responds: “I’m curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of satisfaction. I know we can’t manipulate income level, but I wonder if we could use a multivariate design to see whether this relationship still holds after controlling for participant life satisfaction?” Question: Provide a recommendation to your friend to address her question about whether the relationship holds after controlling for life satisfaction. Include the following details: 1. Discuss the type of multivariate design you recommend and why. 2. Discuss which of the 3 criteria for causality the multivariate design you chose helps to address. 3. Discuss how you would conduct a study to determine whether the relationship holds after controlling for life satisfaction. 4. Identify the predictor(s) and criterion variable(s) in your study.
