保单的数量并不影响其均值,但是会影响其标准差,所以这条曲线非常陡峭,而这就是保险的核心原理

Number of policies doesn't affect the means but it affects that standard deviation, so it becomes very collapsed and this is the basic core idea of insurance.

例如，可能需要自常态分配数量之产生样本或需要计算大量资料的标准差或绘制直方图。

For example, one may need to generate samples drawn from a normally distributed population or may need to compute the standard deviation of a large data set or plot a histogram.
