The experimental research method involves the manipulation of variables by the researcher.
There are two fundamentals of the experimental research method
Manipulation of independent variables:
This means that the researcher tries to systematically change the independent variable to observe and document its subsequent effect on the dependent variable. This allows them to find whether their relationship is direct, indirect, or non-existent.
Control of extraneous variables:
All variables other than the independent and dependent variables are called extraneous variables. In order to accurately observe their mutual relationship, these must be controlled to the best of the researcher's abilities.
