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。
The normal population characteristics, such as the mean, standard deviation, percentile, percentage and coefficient of variation, are often tested in engineering.
正态母体特征值（母体均值、百分位值、百分率、标准差和变异系数等）的检验是工程中常见的问题。
