预防医学论文中常用统计学方法对资料的信息进行收集、整理和分析、正确使用统计学方法是论文具有科学性的重要保证.本文针对期刊来稿中常见的统计学方法问题分析如下:1 有关相对数问题1.1 计算相对数的分母过小.调查和实验的样本数(例数)要有一定数量,数量较多,计算的相对数可靠性才大.例数少时,一般不用百分率表示,使用绝对数(或分数)表示较好.例如“5人全部治愈”、“6份样品超标 Statistical methods used in preventive medicine articles to collect, collate and analyze information, and use statistical methods correctly are important scientific guarantees. The analysis of the statistical methods that are common in journal articles is as follows: 1 Number problem 1.1 The denominator of the relative number of calculations is too small. The number of samples (number of cases) for investigations and experiments must be a certain number, the number of which is large, and the relative reliability of the calculation is large. When the number of cases is small, it is generally not expressed as a percentage. The number (or score) is better. For example, “5 people are all cured” and "6 samples are out of standard
