非参数检验在儿童群体生长水平比较中的应用

Use of Nonparametric Tests for Comparing the Growth & Development of Different Groups of Children

本文根据儿童群体生长发育资料的特点,提出应用非参数检验对不同儿童群体生长发育状况进行比较。通过实例介绍了符号检验、符号秩和检验、多组资料的秩和检验及多组资料秩和检验的两两比较等非参数检验方法。

According to the characteristics of the data on child growth and development, it is suggested that nonparametric tests can be used for comparing the growth and development of different groups of children. Several methods of nonparametric tests, such as the sign test, signed rank sum test (Wilcoxon's test) and rank sum test of block (Friedman's rank sum test) are introduced and illustrated with practical examples. The method of the use of rank sum test of block for comparison between different groups is also presented.
