Show Summary Details

Quick Reference

A definition that is used for convenience during the conduct of a study. It is intended to be practical and workable under the conditions of the study, although it may or may not be a legally or scientifically valid definition. For instance, an operational definition of a single-parent, mother-led family is operationally useful but may differ from a legal definition of the same family status.
