目前国内外多倾向于用百分位数法对横剖面青少儿身体发育调查资料进行统计、分析,制定青少儿单项体质指标发育评价标准。其根据是,这类资料多数不是正态分布。山西医学院儿少卫生学教研室刘德华副主任在《山西省青少儿体质发育调查研究》一文中指出:“对此次调查的15项形态指标的频数分布都做了正态性检验,在城乡660个年龄组中呈正态分布的只有76个组,占11.52%”。并建议“对山西省学生发育评价不宜用均值±标准差的方法,……最好用百分位数法,与世界卫生组织的建议是一致的。”我认为也可用离差法做统计、分析、
At present, people tend to use the percentile method of cross-sectional survey of physical development of young children statistics, analysis, development of individual assessment of physical development indicators. The basis is that the majority of such information is not normally distributed. Shanxi Medical College, Department of Health and less Hygiene Department, deputy director of Andy Lau, “Shanxi Province Youth Physical Development Survey,” a paper pointed out: “The survey of 15 morphological indicators of frequency distribution have done a normality test in urban and rural 660 Only 76 groups were normal distribution among the age groups, accounting for 11.52%. ” And suggested that “the evaluation of student development in Shanxi Province should not be used with mean ± standard deviation method, ... preferably the method of percentile, and the World Health Organization’s proposal is consistent.” I think that can also be used to do statistics deviation method, analysis,
