Meaning of Validity

The quality of being valid, being sound and well grounded in law.

Validity Alternative Definition

Freedom from vices of substance; effectiveness in point of law.

Definition of Validity

The Canada social science dictionary [1] provides the following meaning of Validity: One of two criteria (the other being reliability) by which researchers judge their results or measurement tools. A valid result is one that accurately measures what it claims to be measuring. Using shoe size as a measurement of intelligence is not a valid measure of intelligence. It lacks face validity since it is not obvious that it is measuring what it claims to measure. One test of validity might be the extent to which your measurements allow you to make predictions about future behaviour. If your measurement of intelligence does not predict how people perform on exams then perhaps it is not a valid measurement of intelligence. See: EXTERNAL VALIDITY / INTERNAL VALIDITY / RELIABILITY in this legal dictionary and in the world encyclopedia of law.
