Randomized control trial (RCT)

R
 

A randomized control trial (RCT) is a study design that randomly assigns participants to an experimental group or a control group. This type of study allows researchers (or evaluators) to assess the direct impact of an intervention on some outcome, while controlling for differences within the population. The method of random assignment, is intended to remove biases between different groups. An RCT is often considered a "gold standard" in research, but is difficult to creat in a real-world setting.
