What are qualities of a contrived observation?

Contrived observations are not based on natural or spontaneous events and are instead planned, often with specific outcomes in mind. Qualities of contrived observations may include being structured, artificially manufactured, or predetermined. They may also be heavily guided by the observer and have a certain data collection process in place. Other qualities of contrived observations may include the use of specific materials or methods that are not commonly seen in natural observations and that are instead created for the purpose of the observation.
