看到一段关于说"标准差"的,顺便翻译了.

原文:
Standard Deviation
Standard deviation is a statistical measure of the extent of variation in a set of data. The standard deviation tells you the extent of the spread of individual items around the average.

The number in the 90% column is shown after a run is completed in the Analysis program, not in the Controller) because it is calculated by sorting all items by value obtained during the run, then identifying the value associated the item at the top 10% of all items.

The CV (Coefficient of Variation) makes the standard deviation number easier to comprehend by representing it as a multiple of the average.


翻译:
标准差
标准差是一种描述一组数据变化程度的统计方法.标准差会告诉你那些个别数据项偏离平均值的程度.

在分析程序里(不是在controller的),"90%"一列的数值是在完成一轮执行后显示的,因为它是通过把运行中获得的所有项目按数值分类而计算得到的,然后识别那些与所有项目中最大10%有关的数值.

如果把CV(变化的系数)作为平均值的倍数来描述的话,可以更加容易理解标准差值.
