In order to analyze the data rationally in the process of teaching study, some statistical methods are used in this paper. By introducing descriptive statistics, parametric hypothesis test, one-way analysis of variances (ANOVA) and correlation analysis, the problem of data analysis in practice can be rationally solved. For illustration, some practical cases are utilized. And the result shows that facing data processing problems, we can draw a right conclusion using apt statistical methods. It will provide scientific bases and methods to process data in teaching study for teachers by following these methods.
