      If a study is well-designed and extraneous and confounding variables are controlled then internal validity should be high. So, every experiment has an IV and a DV. Ideally, all other variables will be controlled so that they can’t vary systematically alongside the IV, affect the DV and bias the results.

      Reliability is necessary for a measure to be valid, but measures can be reliable but not valid (Green, 1992). Validity refers to how well the measure assesses or “captures” what it was designed to measure (Johnston et al., 1992).

      High reliability: Large positive reliability coefficient - .8 or better to guarantee acceptance. Good Validity. Good Convergent Validity: Large, positive, correlations with other measure of the same construct. Good Discriminant Validity: Small correlations with measures of other independent constructs.

      Validity and reliability are two important characteristics of behavioral measure and are referred to as psychometric properties. It is important to bear in mind that validity and reliability are not an all or none issue but a matter of degree. Validity: Very simply, validity is the extent to which a test measures what it is supposed to measure.

      The confidence-weighted scores had higher reliability and higher predictive validity. It might seem reasonable to extend the idea of effective test length to validity, calling it, say, "effective predictive test length." Such a figure would indicate how much longer a test would have to be in order to give the same improvement in prediction, by ...
