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 has decided to examine one of her relationships with a scatterplot to double-check for a curvilinear relationship. Which relationship will be most important for her to examine?
A)Life satisfaction and experience of daily stress
B)Number of friends one has and experience of daily stress
C)Number of friends one has and life satisfaction
D)Life satisfaction, experiences of daily stress, and number of friends one has simultaneously

Question

Quizplus · Accepted Answer

The relationship between the number of friends one has and the experience of daily stress (r = .09, not significant) is the most important to examine with a scatterplot for a curvilinear relationship. This is because the lack of a significant linear relationship (as indicated by the correlation coefficient being close to 0 and not significant) suggests that a linear model may not best describe the data. A scatterplot can help visualize whether a curvilinear relationship exists, which could explain the lack of a significant linear correlation.
