几乎不用怀疑平均值和标准偏差会收到异常值存在的影响，而中间值和IQR所受到的影响则较小。

There is no doubt that both the mean and standard deviation are effected by the presence of outliers, while the median and IQR are much less impacted.

我引用的只是数学计算的一个平均值，而波斯纳的数据却是家庭收入分配的中位数或者说中间点。

The data I cite are arithmetical averages, while, as Posner indicates, his data on household incomes are medians, or midpoints, of the distribution of household incomes.

在理想的情况下，最好让大多数的数据都位于中央位置处(例如，平均值或者中间值)。

In ideal conditions, it is preferable to have the majority of our data as close to a central location (e.g. mean or median) as possible.
