Randomised Control Trials
Randomised Control Trials (RCTs) test a procedure with a randomly chosen sample of the public. In medicine RCTs use double blind methods so that the researchers don’t know which users are receiving the treatment and which are receiving a placebo. RCTs have been increasingly used in fields such as welfare to work. They are often seen as a gold standard for evaluation, but can be unreliable – and are best used in conjunction with other research methods.
