(2) processing the remaining data;
③ When there are too many data, take similar data as a data group, and then conduct research based on these groups;
④ You can try the functions such as cluster analysis in SPSs.

Mathematical modeling is a practice of using mathematical methods to solve practical problems. That is, through the process of abstraction, simplification, hypothesis and introduction of variables. The practical problems are expressed by mathematics, the mathematical model is established, and then advanced mathematical methods and computer technology are used to solve them.
Mathematical modeling comprehensively applies all kinds of knowledge to solve practical problems, which is one of the necessary means to cultivate and improve students' ability to apply what they have learned to analyze and solve problems.
Mathematical modeling is to solve practical problems with mathematical models.
