The Comparison of the Relationship Between Sleep Duration and the Academic Performance of Teenage Students in China and the United States

The impact of sleep lengths on academic performance has always been discussed in different fields, such as psychology and pedagogy. At present, scholars always select individuals from specific ranges. They usually ignore the differences among individuals. Their habits and culture can both be the reasons that influence sleep duration and quality, further affecting academic performance. In the future, scholars can improve the development of students' studies and provide help with education policy through this kind of research. In this study, students from different cultures and backgrounds are compared, and their impact of sleep on learning is examined. Each individual needs to provide data by filling out the questionnaire. According to the answering variables, the difference in the impact is discussed by the scatter plots. In the last, at the same sleep time, students in the United States are predicted to have a higher academic performance than students in China. Excluding the data error and the difference between the scoring criteria, cross-culture, and the background also become the main factors to influence sleep.
