Dr. Yared is interested in memorization techniques and motivation. He splits his participants into four equal groups of 20 people each and gave each participant a list of 30 words to try to memorize in three minutes. Two groups were told to repeat the words silently to themselves and two groups were told to make up a story using the words. Two groups were offered 10 cents per word they recalled and two were offered $1 per word. The table shows how many words each group was able to recall. Memory Technique Memory Technique Repetition Make up a story Monetary reward 10 cents per word recalled 11 17 Monetary reward 1 dollar per word recalled 10 19 What are the marginal means for memory technique?

Dr. Cheong is a clinical psychologist who is curious about how people deal with natural disasters (e.g., hurricanes, tornados, earthquakes). His previous research suggests that there is a relationship between how much people feel their emotional well-being was affected by the natural disaster and their likelihood of developing posttraumatic stress disorder (PTSD) symptoms. However, he is curious as to whether the effect of emotional well-being occurs because people receive different levels of social support. He conducts a study in which he asks 174 men and women affected by Hurricane Sandy (2012) to report on how their well-being was affected by the hurricane, the social support felt after the storm, and the number of PTSD symptoms. Dr. Cheong finds support for his proposed relationship. However, in examining his data more closely, he finds that the relationship between emotional well-being and PTSD symptoms is stronger for men than for women. State Dr. Cheong’s hypothesis for this study, describing how each variable relates to the others.

Dr. Finkel is a social psychologist who studies romantic relationships. Several researchers have found that there is a link between income and marital satisfaction (e.g., Dakin & Wampler, 2012). Dr. Finkel is curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of marital satisfaction. He is confident that he cannot reasonably or ethically manipulate people’s income level, so he decides to use a multivariate design. He is also curious as to whether there is a causal link between these two variables or if two other variables (number of arguments and life satisfaction) can explain the relationship. He measures his three variables in a sample of 124 married couples recruited from a local community center. Below are his results: DV: Marital Satisfaction Variable Beta (b) Significance (p) Income .69 .03 Number of arguments –.73 .01 Life satisfaction .13 .81 Which of the following can be concluded based on the results of Dr. Finkel’s study?
