(1)统计学分析方法的选择: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,选用合适的统计学分析方法,不应盲目套用t检验和单因素方差分析;对于定性资料,应根据所采用的设计类型、定性变量的性质和频数所具备的条件及分析目的,选用合适的统计学分析方法,不应盲目套用χ~2检验。对于回归分析,应结合专业知识和散布图,选用合适的回归类型,不应盲目套用直线回归分析;对具有重复实验数据检验回归分析资料,不应简单化处理;
(1) the choice of statistical analysis methods: For quantitative data, should be based on the type of design used, the conditions of data and analysis purposes, the choice of appropriate statistical analysis methods, should not blindly apply t test and one-way analysis of variance ; Qualitative data should be based on the type of design used, the nature and frequency of qualitative variables with the conditions and purposes of analysis, the choice of appropriate statistical analysis, should not blindly apply the χ ~ 2 test. For regression analysis, we should combine the professional knowledge and scatter chart, select the appropriate type of regression, should not blindly apply linear regression analysis; regression analysis with duplicate experimental data test data should not be simplified;
