本文介绍了卫生项目评价的设计方法,并同时介绍了在项目评价中常用的统计分析方法。具体内容如下。1随机化设计的统计方法1.1干预后对照设计假设随机化已保证非实验因素在两组是均衡的。则两组间的差异说明了干预的效果。根据观察指标的测量水平,可采用t检验、秩和检验和x~2检验。
This article describes the design of health project evaluation methods, and at the same time introduced the project evaluation commonly used in statistical analysis. The details are as follows. 1 Statistical Methods for Randomized Design 1.1 Post-Intervention Control Design Assumptions Randomization has ensured that non-experimental factors are balanced in both groups. The difference between the two groups shows the effect of the intervention. According to the measurement of the observed indicators, t test, rank sum test and x ~ 2 test can be used.
