| Abstract: | In this paper, according to the data of mathematical modelling MCM-89 problem in Journol of Mathematics for Technology (General serial No. 50), We establish a model used to distinguish and analyse the new sample′s classification by Fisher judgement method. The result is the same as original′s, but this method does′t need more hypothesis and will be accepted by the students with ease. |
