Apr 19, 2021 · Controlled experiments have disadvantages when it comes to external validity—the extent to which your results can be generalized to broad populations and settings. The more controlled your experiment is, the less it resembles real world contexts. That makes it harder to apply your findings outside of a controlled setting.

Its purpose is to show that changes in one variable (the independent variable) directly cause changes in another variable (the dependent variable).
