论文部分内容阅读
在医学文献中,为了对计数资料进行分析对比,常常要使用率和比。如果率和比使用不正确,无疑会降低文章的科学性。笔者就《贵州医药》1983年第1-6期所载文章中有关这方面比较明显的错误分析如下,以提请大家注意。一.把构成比当作率构成比说明事物内部各构成部分的比重或分布。率说明某种现象发生的频率和强度,是指某种现象实际发生数与可能发生该现象的总数之比。两者不可混淆。
In the medical literature, in order to analyze the count data comparison, often to use rate and ratio. If the rate and the use is not correct, will undoubtedly reduce the scientific nature of the article. The author on the “Guizhou Medicine” 1983 articles 1-6 contained in this article is more obvious error analysis below, to draw your attention. I. The proportion of the ratio as a ratio of the proportion of the internal components of the proportion or distribution. Rate shows the frequency and intensity of a phenomenon, refers to the actual occurrence of a phenomenon and the ratio of the total number of the phenomenon may occur. The two can not be confused.
