By understanding the extent to which each unit of mathematics contributes to the final exam, including the correlation of each unit, it will be possible to identify which units are well understood, and as a result, educational efficiency can be improved. Therefore, we investigated the score rate of each unit in the statistics final exam, the correlation of each unit, and the contribution rate to the final exam, and took measures to improve the score. Moreover, for each unit of linear algebra, we also investigated the score rate of each unit and the contribution rate to the final exam.
