Use the guidelines to evaluate the study. Discuss flaws that you see in the study. A researcher is interested in why Americans have such a high divorce rate. She randomly selects 100 American married couples and 100 Japanese married couples. She invites each couple to come into her office and interviews each couple, asking them about their satisfaction with their marriage. The researcher also notes that a high percentage of the American women had full time jobs outside the home, whereas a high percentage of the Japanese women did not have full time jobs. The researcher concluded that marriages in which the woman has a full time job have a lower rate of success.
