Abstract

It is one of the necessary measures taken by various schools to improve the examination quality, proposition and teaching quality by applying the principles of educational surveying and mathematical statistics to analyze the examination from proposition to examination result. The analysis of students' grades is an important link in the whole teaching process, and it is a necessary thing for teachers. Teachers can get many students' test scores every semester. This paper uses Pearson Chi-square criterion as a sample to test whether the scores obey the standard normal distribution, and takes the analysis results as a reference basis for teaching management. It also tentatively puts forward the treatment method of sample size standardization, which has certain practical significance.
