Abstract
The purpose of this study were to examine the relationship between adolescents’ academic achievement and their life satisfaction using quantile regression and to examine whether there are differences between the results from quantile regression analysis and the results from linear regression analysis. The seventh-wave data of the elementaryone panel (N=2,002) from Korean Children and Youth Panel Survey were used in the analysis. It was found, from quantile regression analysis, that the coefficients obtained from quantile regression analysis vary with the quantile. It was also found that the subjective indicator of academic achievement (satisfaction with academic achievement) is a better predictor of adolescents’ life satisfaction than the objective indicator of academic achievement (school grade).
