Explain two reasons why the research hypothesis is not tested directly.
Does quality of communication improve after people are married? Let’s consider a study by Olthoff (1989) who tested the communication quality of engaged couples three months before and again three months after marriage. In this study, 12 couples received ordinary premarital counseling. We will examine the communication quality of the husbands in this study, where higher scores indicate better communication quality.
