Dr. Guidry conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. She randomly samples 1,500 elderly men and women in Nashville, Tennessee (the state capital), located in the southern United States. Below are her findings.
•Life satisfaction and experience of daily stress: r =.57 (p = .01)
•Number of friends one has and experience of daily stress: r = .09, not sig.
•Number of friends one has and life satisfaction: r = .36 (p = .04)
Dr) Guidry creates a scatterplot of the relationship between the experience of daily stress and life satisfaction. In doing so, she realizes there are three scores that seem to be very extreme and are nowhere near the other points on the scatterplot. Specifically, it appears that three people report very high levels of daily stress and very low levels of life satisfaction. Dr. Guidry should probably consider these scores .
A)random
B)moderators
C)outliers
D)curvilinear scores
