Will fix itself Omission Error - Distorted results: occurs when something (for example data or survey response) is missing Three elements of an experimental study: Responses, variables, experimental units This bias occurs if the sample is not randomized. Measurement When an instrument produces a consistent output, it is: Reliable.
