What's the difference between validation and validity?

Validation


Definition:

  • (n.) The act of giving validity.

Example Sentences:

  • (1) Unfortunately, due to confidentiality clauses that have been imposed on us by the Department of Immigration and Border Protection, we are unable to provide our full names and … titles … However, we believe the evidence that will be submitted will validate the statements that we are making in this submission.” The submission detailed specific allegations – including names and dates – of sexual abuse of child detainees, violence and bullying of children, suicide attempts by children and medical neglect.
  • (2) Recently, the validity of the American Thoracic Society (ATS) standards for selection of spirometric test results has been questioned based on the finding of inverse dependence of FEV1 on effort.
  • (3) Single-case experimental designs are presented and discussed from several points of view: Historical antecedents, assessment of the dependent variable, internal and external validity and pre-experimental vs experimental single-case designs.
  • (4) An application is made to the validity of cancer risk items included in a cancer registry.
  • (5) Although measurements are easily obtained with a tape measure, the validity of these measurements is not known.
  • (6) This observation, reinforced by simultaneous determinations of cortisol levels in the internal spermatic and antecubital veins, practically excluded the validity of the theory of adrenal hormonal suppression of testicular tissues.
  • (7) However, each of the studies had numerous methodological flaws which biased their results against finding a relationship: either their outcome measures had questionable validity, their research designs were inappropriate, or the statistical analyses were poorly conceived.
  • (8) We found no statistically significant difference in one-year, biochemically validated, sustained cessation rates between the group offered the long-term follow-up visits (12.5%) and the group given the brief intervention (10.2%).
  • (9) Although, it did give me the confidence to believe that my voice was valid and important.
  • (10) Both demonstrated concurrent validity and feasibility.
  • (11) Specifically, we apply techniques of data preprocessing, orthogonality constraints, and validation of solutions in a complete TC analysis, for the first time using actual MEP data.
  • (12) However, no evidence could be discerned to support its validity as a measure of a patient's treatment outcome.
  • (13) Validation studies, to show that the method is precise, accurate and rectilinear, have been carried out on four linctus formulations and two pastille formulations.
  • (14) In this paper the domain of validity of the unlabelled and labelled minimal models of glucose disappearance is studied.
  • (15) However, valid electroacoustic evaluation of the DMHAs cannot be accomplished using the conventional hearing aid test box.
  • (16) Validity of the fructosamine assay allows its potential use as a mass screening test for diabetes in these populations (USA, Africa, Caribbean...).
  • (17) Furthermore, CV1% and DV6% have proved to be valid parameters in finding differences in the light reflex in non-age-matched study groups.
  • (18) A role for cAMP in the process of LHRH release was suggested several years ago, but only recently has the validity of this notion come under close scrutiny.
  • (19) However the study does not permit to reach any valid conclusions; further elaborate investigations alone could prove the useful role of genetic influence in the propagation of lepromin sensitivity to the subsequent sibs.
  • (20) From the subcutaneous transplanted tumors a large number of MLuC1-positive tumor cells could easily be recovered, thus indicating the validity of the in vivo methodology.

Validity


Definition:

  • (n.) The quality or state of being valid; strength; force; especially, power to convince; justness; soundness; as, the validity of an argument or proof; the validity of an objection.
  • (n.) Legal strength, force, or authority; that quality of a thing which renders it supportable in law, or equity; as, the validity of a will; the validity of a contract, claim, or title.
  • (n.) Value.
