计划完成程度相对指标的计算,所涉及的问题是比较多的,统计学教材上所罗列的仅仅是其中的很少一部分,这不能不说是当今统计教材的缺陷。而统计学原理作为一门方法性很强的专业基础课,如何尽可能地完善其中的内容,做到能够用其理论指导实践工作,应是统计教材改革的一个方向。 The calculation of the relative index of the degree of completion of the project involves many problems, and the statistics textbook lists only a very small part of it. This can not but be a flaw in today’s statistical teaching materials. The statistical principle as a method of strong basic course, how to improve the content as much as possible, to be able to use its theory to guide practical work should be a direction of statistical teaching material reform.
