RESEARCH STUDY 9.2: Dr. Finkel is а sоciаl psychоlоgist who studies romаntic relationships. Several researchers have found that there is a link between income and marital satisfaction (e.g., Dakin & Wampler, 2012). Dr. Finkel is curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of marital satisfaction. He is confident that he cannot reasonably or ethically manipulate people’s income level, so he decides to use a multivariate design. He is also curious as to whether there is a causal link between these two variables or if two other variables (number of arguments and life satisfaction) can explain the relationship. He measures his three variables in a sample of 124 married couples recruited from a local community center. Below are his results: DV: Marital Satisfaction VariableBeta (b)Significance (p) Income.69.03 Number of arguments–.73.01 Life satisfaction.13.81Which of the following can be concluded based on the results of Dr. Finkel’s study?
