实验研究设计中变量的分析与控制

The Analysis and Control on the Variability in Experiment Study

任何一个科学的实验结论都是从实验中变量所表现出来的数量、质量或状态的事实中推导或分析出来的。变量是实验研究的基本单位也是资料分析和收集的依据。文章在对生物学实验中常见的变量进行详尽分析的基础上,以新教材中典型的生物学实验案例阐释实验中变量的调控方法主要有单因子变量法、对照实验法、平行重复法,以期对生物学的实验研究设计具有很好的促进作用。

Any scientific experiment conclusion is inferred or analyzed from the fact of quantity,quality or condition displayed by the variability in the experiment, The variability is not only the ftmdamental unit of the experiment study, but also the basis of the material analysis and collection. This article carries on the detailed analysis of the common variability in the biology experiment and explains the regulative method of the variahility in the experiment by a typical biology experiment case in the new teaching material, hoping for having a promotion to the designing of the biology experiment study.
