摘要
介绍一种利用中位数、极差和样本量估算均数和标准差的方法,由此使定量资料在Meta分析中得到更好的利用。通过实例分析,示范该估算方法的应用过程。
To introduce a method of estimating the mean and standard deviation based on the median, range and sample size. Therefore, the quantitative data without providing the mean and standard deviation can also be used in a meta-analysis. Examples were given to illustrate how to apply the estimation method.
