我院医学系77级同学在学习医学统计方法的课程中,周长株和黄东平就教材中“率的标准化”方法提出质疑,并写了商榷材料。尽管他们的见解还不甚成熟,立论或有片面,但亦揭示了“率的标准化”有不足之处,应用上有局限性。同学们能够独立思考,敢于提问,是值得赞许的。现就率的应用问题进行讨论,权充答疑。在医学实践和科研中,相对数的应用最广,差错亦最多,原因一般都不在于计算,而在于对几个指标的概念不清,以致张冠李戴或进行对比时不考虑抽样误差,过早下结论;或因
In the course of studying medical statistics methods, Grade 77 students of the Department of Medicine of our hospital questioned the method of “standardization of rates” in the teaching materials of Zhou Yongzhu and Huang Dongping, and wrote commercial materials. Although their opinions are not yet mature and the arguments are one-sided, they also reveal the inadequacies of the “standardization of rates” and limitations in their application. Students can think independently and dare to ask questions. It is worthy of praise. Now we will discuss the application of the rate, and answer the question. In medical practice and scientific research, the relative number is the most widely used and the errors are also the most common. The reason is not that the calculations are generally based on the concept of several indicators. As a result, Zhang Jian Li Dai or the comparison does not consider the sampling error.
