摘要
医学研究中通过对观察对象的特征进行定量化测量而得到的指标称为定量资料,对定量资料分析后的结果有时不可避免的存在错误,如数据类型判断错误,试验方法选择错误,忽略分析前提条件等。本文通过对典型错误进行分析,并从资料的基本因素-数据入手,为读者提供几种对结果进行复查的可行思路。
The data coming from quantifying the characteristics of the objects in the medical research is called quantitative data.The unavoidable errors are often presented in the results of analyzed quantitative data,such as errors on judging data type,errors on choosing statistics methods and ignoring the conditions the methods must satisfy.In this paper,we focused on analyzing the typical errors of quantitative data analysis based on the basic elements-data and provided readers some feasible ideas of reviewing analyzed results.
