Experimental research, also known as experimental research, is a method of collecting direct data.Select appropriate groups, control relevant factors through different means, and test the response difference between groups.Researchers use the principles and methods of scientific experiments.[1]
Experimental research is a controlled research method, which evaluates its effect on one or more variables through the change of one or more variables.The main purpose of the experiment is to establish the causal relationship between variables. The general approach is that researchers put forward a tentative hypothesis of causal relationship in advance, and then test it through experimental operations.[2]

In sociology, there are also different definitions of experimental research. In the book "Modern Social Survey Methods" edited by Professor Feng Xiaotian, experimental research refers to a method that is carefully designed and under highly controlled conditions, researchers study the causal relationship between variables by manipulating certain factors.
