controlled study
Variables are isolated
A controlled study is research that compares outcomes between groups—typically one receiving a treatment and one not—while keeping other variables constant.
The control group provides a baseline, allowing researchers to attribute differences to the intervention rather than chance or outside factors.
The controlled study showed the drug reduced symptoms by 40% compared to placebo.
