Breaking Down Correlational Research

A. A researcher invited a sample of college students to a lab at 1:00 P.M. to take an attentional control test called the Stroop, in which color names are presented in different colors. After finishing the Stroop test, each student wrote down what foods they had consumed in the previous hour, and the researcher figured out how many calories each student had eaten.

Make a scatterplot of the data in the table below (5 pts). What kind of association is thispositive, negative, or zero (5 pts)? Does the association seem strong or weak (5 pts)? Do you notice any outliers (5 pts)?

Person	Stroop test score (seconds to complete)	Calories consumed at lunch
A	100	550
B	120	200
C	150	210
D	80	600
E	85	750
F	90	400
G	60	575
H	120	325
I	110	350

B. Plot this relationship: The number of daily stressors is associated with lower emotional well-being. Can you imagine any possible moderators of the finding that "number of daily stressors is associated with lower emotional well-being"? (10 pts)

Possible moderator variable: ______________________________________________

Relationship between daily stressors and emotional well-being

C. If there is no association between two variables, can you make a causal claim? (10 pts)
