在检查结果以了解它们如何分布时，通常会构建一系列直方图，以显示有多少位于特定范围内。如果结果是正态分布的，预计：2.3%将小于平均值-2.0 SD(标准差)或大于平均值+2.0 SD；19.2%介于平均值-0.5 SD和平均值之间，或平均值和平均值+0.5 SD之间，等等。然后可以比较观察到的分布和预期的分布，以了解这些分布有多不同。
When examining results to see how they are distributed it is common to construct a series of histograms showing how many lie within a particular range. If the results were normally distributed it would be expected that: 2.3% would be less than the mean-2.0 SD (standard deviation) or greater than the mean+ 2.0 SD; 19.2% would lie between the mean- 0.5 SD and the mean, or between the mean and the mean+ 0.5 SD, etc. Itis then possible to compare the observed and expected distributions to see how different these are.
