An OT educator, investigating the degree of relationship between student scores on a battery of personality tests and performance in OT graduate school, gave a random sample of 50 applicants accepted for admission to an OT school a personality inventory evaluation. At the end of the first year, college grade point average (GPA) was also recorded for each of the 50 students in the study. What statistical procedure is appropriate for assessing degree of association between personality scores and freshman...
