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.
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。
Because the requirements for many nutrients are not normally distributed, other considerations of population variability frequently are necessary.
由于很多营养素的需要量不是正态分布的，那么人群其他的变异频率就有必要考虑了。
