Suppose you are conducting an experiment to determine whether a new meditation technique significantly reduced anxiety levels in people who live in the city (at the 0.01 level). In order to maximize the chance that participants in your study will actually try the new meditation technique, you go to a few yoga studios in your neighbourhood and assign participants to either the meditation condition or the control condition as they walk in for their yoga session. The participants in the meditation condition use the new technique during the last ten minutes of their yoga practice, while control participants just close their eyes for the last ten minutes. All participants complete a 10-point anxiety questionnaire after their practice, and you record the overall anxiety score based on their survey responses. Your experiment has the power to correctly support your research (knowing that it is true) 82% of the time.
