To measure the relationship between anxiety level and test performance, a psychologist obtains a sample of n = 6 college students from an introductory statistics course. The students are asked to come to the laboratory 15 minutes before the final exam. In the lab, the psychologist records physiological measures of anxiety (heart rate, skin resistance, blood pressure, etc.) for each participant. In addition, the psychologist obtains the exam score for each participant. Compute the Pearson correlation for the following data:

Student Anxiety Rating Exam Score

A 5 80
