Validity
In science and statistics, validity is the extent to which a concept, conclusion or measurement is well-founded and corresponds accurately to the real world. The word "valid" is derived from the Latin validus, meaning strong. The validity of a measurement tool is considered to be the degree to which the tool measures what it claims to measure.The above text is a snippet from Wikipedia: Validity (statistics)
