Randomized Controlled Trial
An experiment in which participants are randomly assigned to treatment or control conditions to estimate an effect without bias.
A randomized controlled trial, or RCT, combines random assignment with a control condition. Randomization balances the groups on measured and unmeasured characteristics, so post-treatment differences can be attributed to the intervention. Well-run trials also specify outcomes in advance and, where possible, blind participants and assessors to reduce expectation effects. RCTs are the reference standard for effectiveness questions in medicine, education, and policy research.
Few theses can mount a full-scale trial, but understanding RCT logic still matters: it defines the benchmark your own design approximates and the standard by which the intervention literature you review should be judged. If you do run one, report the randomization method, the flow of participants, and any dropout, since these details determine how credible the causal claim is.
