The main features of the experimental method are the strict control of independent variables and experimental conditions, the active elicitation of phenomena to be examined, the analysis of the results, and the derivation of a correlation between the independent variable and the dependent variable.

There are four basic characteristics of the experimental method, which are the purposeful manipulation of the independent variable, tight control of the experimental process, a rigorous experimental design and procedures, and the possibility of repeating the experiment in the same situation in order to verify the reliability and validity of the results.

The experimental method is to carry out a marketing method of small-scale experiments, and then analyze whether this real-world marketing method is worth the large-scale promotion of a method, which is characterized by a number of factors affecting the marketing of one or two factors, observe and analyze the differences between them and the marketing campaign.

The researcher makes a subjective judgment based on some theory or empirical fact, first assuming that phenomenon A is the cause of phenomenon B, and then observing the change of B by proving this assumption through experiment.

The general logical principle of the experimental method is to measure B before it is affected by A, then to apply an experimental stimulus A and keep all other conditions exactly the same, and then to measure B after it has been affected by A. The experimental method is based on the idea that A is the cause of B and that B is the cause of B.

Finally, the existence of a causal relationship between A and B is determined by comparing the results of the two measurements before and after the deduction for differences. If there is a change between the two before and after conditions, it can be tentatively assumed that A is the cause of the change in B, i.e., A-B.
