【摘要】：正1.资料的表达与描述:用均数±标准差表达近似服从正态分布的定量资料,用中位数及四分位间距表达呈偏态分布的定量资料;用统计表时要合理安排纵横标目,注意不要犯主谓倒置的错误;用统计图时所用统计图的类型应与资料性质相匹配并使数轴上刻度值的标法符合数学原则;用相对数时分母不宜小于20,要注意区分百分率与百分比。2.统计分析方法的选择:对于定量资料,应根据所采用的设计类型、资料所具备的条件和分析目的选用合适的统计分
[Abstract]:Regular 1. Data expression and description: the quantitative data from normal distribution were expressed with mean 卤standard deviation, and the quantitative data with skew distribution were expressed with median and quartile spacing. When using statistical tables, we should arrange the vertical and horizontal items reasonably, pay attention not to make the mistake of subject-predicate inversion, and the types of statistical charts used in statistical charts should match the nature of the data and make the scaling method of scale value on the number axis conform to the mathematical principle. When using the relative number, the denominator should not be less than 20, we should pay attention to distinguish percentage and percentage. 2. Selection of statistical analysis methods: for quantitative data, appropriate statistical scores should be selected according to the type of design used, the conditions of the data and the purpose of analysis
