Quizplus · Accepted Answer

While there may be some correlation between IQ and academic performance, and between gender and IQ, the most significant correlation in this study is likely to be between self-discipline and academic performance. This is because research has consistently shown that self-discipline and self-regulation are powerful predictors of academic success, even more so than IQ or innate intelligence. Therefore, Dr. Tremblay is likely to find a strong relationship between the self-discipline levels of her ninth-grade participants and their academic performance.
