Experimental Design
The process of planning an experiment to ensure that the results are valid, typically involving the manipulation of one or more independent variables to observe their effect on a dependent variable.
Implications
A research method used to test hypotheses by manipulating one or more independent variables and observing the effect on dependent variables, often used in scientific research, marketing testing, and product development to establish causal relationships.
Example
Example: A pharmaceutical company uses experimental design to test the efficacy of a new drug, randomly assigning participants to treatment and control groups to observe differences in outcomes.

Different from observational studies, which only observe without intervention, experimental design actively manipulates variables to establish cause-and-effect relationships.
