This paper first points out some problems in assessing the results of educational practice, then proceeds to suggest, from the point of view of discriminate analysis and optimal partition in multivariate tactical analysis, the optimized method for such assessment with the help of examples.

Based on the concept of the optimal partition,the characters of the optimal value function and the critical regions for linear programming problem with higher-dimensional parametric cost coefficients are studied.

Mathematics geological study is also applied to stratigraphic classification using multi\|variable optimum partition.

<abstract>e comprehensive method of the element - stratum , optimum division and the filtration in classifying forma tions in Mesozoic of Jiyang depression is tried out .

In this paper, by using the principal component analysis and optimal sorting method, we get a solution for the assessment of educational practise and then give the calculation of a example.

Successive optimum dichotomy of logging series based on mean value of single layer;

This paper carries out the grade evaluation for college students according to the value of the synthetic evaluation by means of the optimal partition method of multivariate statistical analysis so as to get rid of the problems caused by the personal factors and enrich the theory of quantified grade evaluation for the college students.
