总量指标动态数列平均发展水平计算方法的优化

Optimization of Computing Method of Total Index Dynamic Sequence Average Development Level

总量指标动态数列平均发展水平的计算方法是最基本的,它是计算相对数或平均数动态数列平均发展水平的基础。现行总量指标动态数列序时平均数的计算公式有四个,正确的使用公式需要学生有一定的数学基础和较强的逻辑推理能力才能很好的应用,针对中职学校学生学习的困难,对计算方法进行了优化。

The comuting method of total index dynamic sequence average development level is basic for computing the dynamic sequence average development level of relative number or average number. There are four calculation formulas of average number of total index dynamic sequence. Correct use of formulas need students have certain mathematical foundation and strong ability of logical reasoning. In view of the secondary vocational school students＇ leaming difficulties, the paper studies the optimization of the calculation method.
