A control group is a set of study subjects that does not receive the treatment or change being tested, providing a baseline to show what happens without the intervention. For investors, control groups matter because they help determine whether reported benefits are real or just coincidence or outside influences—think of testing a new recipe by comparing it against the original to see if the change truly improves the result.
