A randomized controlled trial (RCT) is a scientific study designed to evaluate the effectiveness of an intervention or treatment by randomly assigning participants to either a treatment group or a control group. This randomization helps eliminate bias and ensures that any differences in outcomes can be attributed to the intervention itself rather than other factors. RCTs are considered the gold standard in clinical research due to their ability to provide robust evidence for causal relationships. They typically involve rigorous protocols and can be used in various fields, including medicine, psychology, and education.
