Application of Research on Decision Tree Algorithm for Sports Grade Analysis

ABSTRACT

This paper introduces and analyzes the data mining in the management of students' sports grades. We used the decision tree in the analysis of grades and investigated attribute selection measures including data cleaning. We took sports course score of some university for example and produced decision tree using ID3 algorithm which gives the detailed calculation process. Because the original algorithm lacks termination condition, we proposed an improved algorithm which can help us to find the latency factor which impacts the sports grades.
