Comparison of the Influence of Sleep Duration on Learning of High School Students in Public Schools and International Schools based on Z-test

Adequate sleep is essential for adolescents' cognitive function and academic performance. This study examines the relationship between sleep duration and academic outcomes among senior high school students. The data in this study were collected from 10th and 11th-grade students in international schools in Qingdao and Dalian. A one-sample z-test for proportion assessed whether a significant number of students slept less than six hours per night. Results indicated that a substantial proportion of students experienced insufficient sleep. However, no significant correlation was found between sleep duration and academic performance, suggesting that other factors may influence academic outcomes. Instead, the results suggest that factors beyond school typesuch as time management, extracurricular commitments, and individual lifestyle choicesmay play a more crucial role in determining students' sleep duration. These findings underscore the need for further research to explore additional variables affecting students' academic achievements.
