This study was undertaken to determine whether a significant correlation exists between the student's performance on the Advanced Placement (AP) Computer Science Examination and three factors: (1) mathematics scores on the Preliminary Scholastic Aptitude Test (PSAT); (2) a mathematics index score reflecting mathematics courses taken by the student in high and his/her grades in those courses; and (3) the student's overall grade point average. The data were analyzed by calculating the Pearson product-moment correlation between the scores on the AP examination and the selected factors. A significant correlation at the 5% level was found for the selected factors. Only the highest correlating factor, the PSAT mathematics score, was selected for a regression formula after it was found that the inclusion on the other factors did not contribute significantly to the quality of the prediction. Four appendices provide tables displaying the data collected for the study and a description of the data analysis process. (Author/EW)
