如何实现从样本量、中位数、极值或四分位数到均数与标准差的转换

How to estimate the sample mean and standard deviation from the sample size, median,extremes or quartiles?

本文简要介绍在Meta分析中如何使用样本中位数、最小值和最大值等综合统计量(summary statistics)来估算连续性数据的样本均数与标准差的方法,并选取了一组真实的案例数据估算样本均数与标准差,以作示例。

This article introduces the methods about how to use the summary statistics such as the sample median, minimum and maximum to estimate the sample mean and standard deviation for continuous outcomes. For the purpose of illustration, we also apply the existing methods to a real data example
