那么这些异常值和分散度是怎么影响度量值和标准偏差的呢？

So how do these outliers and dispersion affect the values of the mean and standard deviation?

当然，对于此途径存在着由，例如，寻找缺陷并执行异常路径的测试引起的偏差。

Of course, there are deviations to this path that can be caused, for example, by the test finding a defect and executing an exception path.
