Description
PSYC 2040 Multiple Regression An educational psychologist was interested in examining the predictors of success for an Engineering exam. Previous research had led her to believe that the best predictor of exam success was the number of hours students spent reading the text. She wanted to test the extent to which the number of hours spent on practice questions could increase prediction of exam grades (beyond just using hours spent reading the text). As well, she wanted to test the exten t to which the amount of sleep a student obtained the night before an exam could increase prediction of exam grades (beyond just using hours spent reading the text). The data from this fictitious study are on the CourseLink website: Column 1: Final exam grade (grade) Column 2: Number of hours spent reading the text (study) Column 3: Number of hours of sleep the night before the exam (sleep) Column 4: Number of hours spent doing practice questions (practice) Part I: The Substantive Question Write a short APA style report that (1) identifies the best predictor (s) of grade and (2) includes the results of two multiple regression analyses. The first regression analysis should assess (a) the proportion of variance in grade that is accounted for by using both study and sleep and (b) the proportion of variance grade that is uniquely predicted by sleep. The second regression analysis should assess (a) the proportion of variance in grade that is accounted for by using both study and practice and (b) the proportion of variance in grade that is uniquely predicted by practice.
