SCENARIO: Dr. Rodriquez is considering conducting a study examining whether people who score higher on a measure of narcissism have poorer romantic relationships. One of her first tasks is to determine each participant’s level of narcissism. She decides to use a narcissism scale created by a colleague, the Donal Scale. Question 1 of the Donal Scale reads, “I think about myself much more than I think about others.” Question 2 of the Donal Scale reads, “I do not have a high opinion of myself.” Question 3 of the Donal Scale reads, “Other people think I am really special.” Participants are asked to respond to these items using a 1 (strongly disagree) to 5 (strongly agree) scale. 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. She then compares the scores between the two time points. This is a test of __________________. Dr. Rodriguez then examines 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 scatterplot indicates _______________________.
