Cоnsider the fоllоwing reseаrch study: Dr. Hernаndez is conducting а research study to see if communication skills training will improve marital satisfaction. He recruits 50 married couples to participate in his study. First, he gives them a survey to test how happy they are in their marriage. Then, he randomly assigns half of the couples to participate in a 2-hour training on communication skills. The remaining couples receive no training. Three months later, he gives all couples the same survey to test how happy they are in their marriage. He notices that couples who participated in the 2-hour training on communication skills rate their marriage satisfaction higher than couples who did not participate in the training. Thus, he concludes that participation in the 2-hour training on communication skills improves marital satisfaction. What is the dependent variable of this study?
