Abstract
To improve the sports mental behaviours of college students is a subject that should be studied for every physical education teacher in colleges. Cluster analysis can classify samples and help the teachers to adopt the hierarchical teaching model to improve the sports mental behaviours. This paper analyses the necessity of cluster analysis of sports mental behaviours of college students and elaborates the concept and methods of cluster analysis. The process of sports mental behaviours classification of college students based on cluster analysis include four steps of indexes selection, data collection, clustering analysis and result analysis. According to the different psychological behaviour of college students, we use cluster analysis to classify the students into class A, class B and class C to use different kinds of teaching methods for different kinds of students. The cluster analysis based on the psychological behaviour of college students has important reference significance for improving the quality of physical education in colleges.
