A researcher is interested in interpersonal attraction and the factors that affect it. She designs a study in which she looks at the effect of similarity and social warmth on interpersonal attraction. Participants in her study meet a target person who either is or is not similar to the participant (the similarity variable) and who is either friendly or is aloof (the social warmth variable). After interacting with the target person under these conditions, participants are then asked to rate how attractive they think the target person is. What is the null hypothesis in this study? A) Similarity and social warmth have no effect on interpersonal attraction. B) Similarity and social warmth have a positive effect on interpersonal attraction. C) Similarity has a positive effect on interpersonal attraction, but social warmth does not. D) Similarity has no effect on interpersonal attraction, but social warmth has a positive effect.
Patrice randomly assigns thirty couples to a problem-solving skills training group and another thirty couples to a group where they have group discussions about their relationship problems, but no specific training is provided. She assesses positive and negative problem-solving behavior before and after the groups, and she finds that after the groups, couples in the skills training group have higher positive and lower negative behavior scores than couples in the discussion group. What can Patrice conclude from this? A) Patrice can conclude nothing; she has to conduct statistical analyses to determine whether there is a significant difference between her groups. B) Patrice can conclude that her skills training program improves behavior because she conducted a controlled experiment. C) Patrice can conclude nothing until she conducts a meta-analysis of her results. D) Patrice can conclude that the skills training program improves behavior, and that this finding is not due to chance.
