十、医学实验设计进行医学实验必须有实验设计,任何科学研究工作都是通过科研设计、科研实践和资料处理三个阶段来完成的。良好的实验设计不仅是整个实验工作的依据和资料处理的先决条件,也是使实验获得预期结果的重要保证。实验设计的意义在于用比较少的人力物力在较短的时间取得比较多的信息,缩小研究中不可避免的误差,消灭可以避免的误差;经过统计处理可以取得一个关于误差大小的估计,明确回答要研究的问题。现将医学实验设计中的重要内容概述如下。
X. Medical experiment design Medical experiment must have an experimental design. Any scientific research work is accomplished through three stages: scientific research design, scientific research practice, and data processing. A good experimental design is not only the basis for the entire experimental work and the prerequisite for data processing, but also an important guarantee for the experiment to obtain the expected results. The significance of the experimental design is to obtain more information in a shorter time with less manpower and material resources, reduce the inevitable errors in the study, eliminate the errors that can be avoided; after statistical processing can obtain an estimate of the size of the error, a clear answer Questions to study. The important contents of the medical experiment design are summarized below.
