In this paper we analyze the marks of the 2003 grade students and give some explanations to the results. Three parts are included as follows:(1) In the first chapter we study the 2003 grade students" math term marks and their cet-4 marks according to their entrance marks by using the clustering analysis of ordered sample. From the results we find some factors that affect the students" marks. And we also prepare for the analysis of variance that include quantitative variable.
