Step-by-step explanation:
Crum and Langer Experiment:
- Conducted in 2007, Crum and Langer's Hotel experiment was designed to test the hypothesis that changing people's perceptions and beliefs about a particular exercise or physical activity would incur actual health benefits.
- Crum and Langer picked the participants from the staff of seven similar hotels.
- The participants who were informed about the health benefits of cleaning and housekeeping work were the experimental group. An experimental group is a sample or participant group that receives a particular treatment. The experimental group helps to determine the effects of a treatment (in this case, information regarding health benefits of cleaning).
- The control group is a group of participants that does not receive the treatment. The uninformed group that did not receive the information about the health benefits of housekeeping work.
- As a result, the experimental group showed health improvements whereas the uninformed group showed no significant changes in health status.
