[1540–50; < Late Latin] Validity hold water To be valid, sound, and defensible; to show no inconsistency or deficiency when put to the test. As early as the beginning of the 17th century, this expression was used figuratively of arguments, statements, etc., although both hold and water can be taken literally to describe a vessel or other receptacle’s soundness in retaining a liquid. Let them produce a more rational account of any other opinion, that will hold water … better than this mine doth. (John French, The York-shire Spaw, 1652) a leg to stand on Viable proof or justification; something on which to base one’s claims or attitudes. A leg pro vides support and helps to maintain balance. Figuratively this expression is most often heard in the negative not have a leg to stand on, referring to one who fails to support his attitudes or behavior. It is frequently used in legal contexts where an inability to provide proof or justification is pronounced. The still current expression dates from the 16th century.

validity[və′lid·əd·ē] (mathematics) Correctness; especially the degree of closeness by which iterated results approach the correct result. validity the extent to which a measure, indicator or method of data collection possesses the quality of being sound or true as far as can be judged. For example, if a psychological measure, such as an intelligence test, is considered to be valid, this means that it is thought to measure what it sets out to measure. If social survey observations are said to have produced valid data, then they are considered to be true reflection of the phenomenon being studied in the population being studied (e.g. projections of voting behaviour), and the survey method could be said to have validity. Compare RELIABILITY. In practice, in sociology and the social sciences generally, the relation between indicators and measures on the one hand and the underlying concepts they are taken to represent is often contested (see OFFICIAL STATISTICS, MEASUREMENT BY FIAT). validity
