- | 实验研究的目标是要确定两个不同变量之间的因果关系,即一个变量的变化是不是由另一个变量的变化引起的。实验研究一般有两个特征:1.研究者需要变化其中一个变量,也就是自变量(independent variable),来观察另一个变量,也就是因变量(dependent variable)的变化。2。研究者在改变自变量时,需要对实验中的其他无关变量进行控制,确保它们不会影响实验的结果。 | + | |

+ | The aim of experimental research is to ascertain the causality of two different variables, that is to say, to ascertain whether the changes of one variable is caused by the changes of another one. Experimental research usually have two main features: 1. Researcher need to change one variable(independent variable) in order to observe the changes in another one(dependent variable). 2. The same time changing the independent variables, researchers should also control the irrelevant variables, making sure they won't affect the result of the experiment. | ||
