Influence of Sleep Quality on Mathematics Performance: An Experimental Study

This quasi-experimental study examined the influence of sleep quality on students’ mathematics performance over a three-month period. A total of 78 junior high school students participated in the study. Their sleep quality was assessed monthly using the Pittsburgh Sleep Quality Index (PSQI), while mathematics performance was measured through test scores administered in January, February, and March. Statistical analyses were used to examine the relationship between sleep quality and academic achievement, as well as differences in sleep quality across socio-economic status and sex. The Pearson correlation analysis revealed no significant relationship between PSQI scores and mathematics test scores. Furthermore, a one-way ANOVA showed no significant differences in sleep quality across socio-economic groups, and an independent samples t-test indicated no significant difference between male and female students. These results suggest that sleep quality did not significantly impact mathematics performance in this context. It is recommended that future research include larger and more diverse samples, extended study durations, and additional variables such as stress levels, screen time, and study habits to better understand the factors influencing academic achievement.
