Definition
A valid experiment is a research method that accurately measures the effect of an independent variable on a dependent variable. It ensures that the results obtained are reliable and can be generalized to the larger population.
A control group is a group in an experiment where participants do not receive any treatment or manipulation. It serves as a baseline for comparison with the experimental group.
