The range is the measure of variability typically presented with the means of interobserver agreement scores of behavioral data. However, the range by itself yields little information about the individual interobserver agreement scores before they were averaged. The standard deviation, on the other hand, is a measure of variability that provides the researcher and reader with information regarding the dispersion of scores, allowing a more thorough interpretation of the interobserver agreement mean. The case is presented for the adoption of the standard deviation as an adjunct to the range in reporting the mean of interobserver agreement scores.
极差是变异性的一种度量，通常与行为数据的观察者间一致性得分的均值一起呈现。然而，极差本身在对个体观察者间一致性得分进行平均之前，几乎无法提供有关这些得分的信息。另一方面，标准差是一种变异性度量，它为研究者和读者提供有关得分离散程度的信息，从而能对观察者间一致性均值进行更全面的解读。本文阐述了采用标准差作为极差的补充来报告观察者间一致性得分均值的情况。
