Planning research

Researchers plan and carry out studies in a way that ensures results are accurate and not caused by chance.

They do this by following strict guidelines. They also have to reduce the risk of their own – or participants’ – ideas or beliefs about the research unfairly influencing (biasing) the results. This section describes some methods used to make sure studies are fair and reliable. Some information applies to clinical trials only.
