一、为什么要实验?在经验性研究中,研究人员从“现实”世界中收集数据,进行分析,并测试有关假设的有效性。实验研究是一种经验性研究。如果研究目标是得出可靠的“因果”关系,实验研究比其他研究方法更为人看好。如果要充分说明某些事件是由某些事件引起的(不仅是相关),最好的办法就是由实验来检验。当然,“原因”是科学研究中最难发现的东西之一。然而,科学是以技术方法解决实际问题的知识,它要说明因果关系。从实用角度看,如果能说明在A 事件发生后,一定会发生B 事件,就可以预测因果关系了。要了解上述情况,实验是最好的检验方法。实验方法和其它研究方法不同的地方
First, why do experiments? In empirical research, researchers collect data from the “real world”, analyze it, and test the validity of the hypotheses. Experimental research is an empirical study. If the research goal is to derive a reliable “causal” relationship, experimental research is more promising than other research methods. If you want to fully demonstrate that some events are caused by some event (not just related), the best way is to test by experiment. Of course, “cause” is one of the hardest things to discover in scientific research. However, science is the technological solution to practical problems, and it explains the causal relationship. From a practical point of view, a causal relationship can be predicted if it can be shown that there must be a B incident after the A incident. To understand the above situation, the experiment is the best test method. Experimental methods and other research methods in different places
