Citizen Science, data quality, data validation


Data quality is a primary concern for researchers employing public participation in scientific research, or “citizen science,” to accomplish data collection and analysis tasks. This mode of scientific collaboration relies on contributions from a large, often unknown population of volunteers with widely variable expertise. In this paper, we review the commonly employed mechanisms for ensuring data quality. We also discuss results of a survey of citizen science projects that reports on the use of some of these mechanisms, noting that it is most common for projects to employ multiple mechanisms to ensure data quality and appropriate levels of validation.
