What Is an Experimental Research Design?

Experimental research, also called experimental research, is a method of collecting direct data. Select appropriate groups, control related factors through different means, and test the difference in response between groups. Researchers use the principles and methods of scientific experiments. The main purpose is to establish a causal relationship between variables. The general practice is that the researcher puts forward a tentative hypothesis of causality and then tests it through experimental operations. It is a controlled research A method that evaluates its effect on one or more variables by changing one or more variables. ^[1]

"Experimental Research" in Educational Psychology: It is a way to explore the relationship between independent and dependent variables in a control context.

The definition of experimental research in sociology is also different. In Professor Feng Xiaotian's book "A Survey of Modern Society", experimental research refers to a carefully designed and highly controlled condition Next, researchers manipulate some factors to study the causal relationship between variables.
