Control Experiment

Definition: A "control experiment" is a type of scientific experiment that is designed to test how one specific factor (or variable) affects the outcome of the experiment while keeping other factors constant. In simpler terms, it helps scientists understand the effect of one thing by comparing it to a situation where that thing is not present.
