Holding a variable constant ensures that the variable will not vary between groups, thus eliminating the possibility that it will become a confound. If a variable is allowed to vary between groups, it may be responsible for any differences observed between those groups, making it difficult to determine the true cause of the differences. By holding the variable constant, this possibility is eliminated, allowing for a clearer interpretation of the results.
