4.Research shows that similarity in attitudes, beliefs, and interests plays an important role in interpersonal attraction. Thus in theory, one's attitude should be similar to that of his/her relationship partner. Suppose a researcher developed a questionnaire that measures how liberal or conservative one's attitudes are. Low scores indicate that the person has liberal attitudes, whereas high scores indicate conservatism. The following hypothetical data are scores for married couples.

D 4 7
