Abstract
This study deepens our understanding of the prediction and structural relationship between a student’s academic performance and his/her regular after-school exercise by estimating models based upon the quantile regression and the instrumental variable quantile regression methods, respectively. Using data on Korean middle school students, we found that negative relationships were dominant for the prediction models, whereas the relationships were reversed for the structural models, affirming the theoretical and experimental hypotheses observed in prior literature. Furthermore, we also found that the low-performing students, in terms of the academic performance, had stronger associations between the two variables than the high-performing students, overall.
Highlights
After-School Exercise and the Investigating the relationship between mental health and physical activity has been a popular research topic in literature
The goal of this study is to empirically identify the relationship between students’ academic performance and their after-school exercise by separately estimating structural models for the students belonging to different groups, thereby deepening the prior empirical results on the two variables
For the purpose of this study, we investigated the empirical data collected by the National Youth Policy Institute (NYPI) in Korea from middle school students in 2011, using both quantile regression (QR) and instrumental variable quantile regression (IVQR)
Summary
After-School Exercise and the Investigating the relationship between mental health and physical activity has been a popular research topic in literature. The goal of this study is to empirically identify the relationship between students’ academic performance and their after-school exercise by separately estimating structural models for the students belonging to different groups, thereby deepening the prior empirical results on the two variables. For this purpose, we classified the students according to the quantile levels of their academic performance score and examined whether the students belonging to each quantile level behaved according to the hypothesized theory or not. This study contributes to the literature by providing empirical evidence on the positive structural relationship between Korean middle school students’ physical activity and their academic performance by applying the IVQR method.
