Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Donal scale. Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special."
Before using the measure in her study, Dr. Rodriquez gives the measure to a group of participants on the first day of the semester and again on the last day of the semester. Dr. Rodriquez is examining the scatterplot of the data she collected on the first day of the semester and the last day of the semester. On the scatterplot, she sees that the dots are very close to forming a diagonal line. This indicates which of the following?
A)A strong relationship
B)A nonrelationship
C)A valid finding
D)A negative finding

A scatterplot with dots forming a diagonal line indicates a strong relationship between the two variables being plotted. In this case, Dr. Rodriguez likely plotted the scores on the Donal scale from the first day of the semester and the last day of the semester to assess test-retest reliability. The fact that the dots are forming a diagonal line suggests that there is a strong positive relationship between scores on the two administrations of the measure, indicating good test-retest reliability.
