在对危地马拉学龄前儿童进行的持续纵向调查的背景下，收集了18个不同人体测量维度的测量变异性估计。给出了每个变量的总测量方差、观察者内方差和短期受试者内方差的估计。描述了一种在横断面和纵向调查中评估测量方差的简单程序，其中总测量方差表示为适当的受试者间方差的百分比。这一统计数据是人体测量变量相对再现性的一个指标。
Measurement variability estimates for 18 different anthropometric dimensions were collected within the context of an ongoing longitudinal investigation of preschool Guatemalan children. Estimates of total measurement variance, intra‐observer variance, and short‐term intra‐subject variance are presented for each variable. A simple procedure for the evaluation of measurement variance in cross‐sectional and longitudinal investigations is described in which the total measurement variance is expressed as a percentage of the appropriate inter‐subject variance. This statistic serves as an index of the relative reproducibility of anthropometric variables.
