| Abstract: | Based on the knowledge of probability statistics, a new method for the optimal classification numbers in drawing histogram is found and its computer program is also given in this paper. This program can quickly calculate the most reasonable dividing group numbers, frequency items, cumulative frequency in constructing histogram and has a normal distribution test for data effectively. |
