AP Potential

The table below shows the number of students that participated in the study, the section(s) of the PSAT/NMSQT that were used to predict performance, and the correlation between PSAT/NMSQT performance and AP performance for each AP Exam. A correlation measures the strength and direction of the relationship between two variables, in this case, PSAT/NMSQT scores and AP exam scores. Correlation values range from -1 to +1 with absolute values of approximately 0.1 considered to represent a small relationship, absolute values of approximately 0.3 considered to represent a moderate relationship, and absolute values of 0.5 or higher considered to represent a strong relationship. A positive correlation, like those seen between PSAT/NMSQT scores and AP exam scores, indicates PSAT/NMSQT scores are useful for identifying students who are likely to do well in AP courses and exams.
