That is, if a validitycoefficient such as the correlation between a target test and another test is high, reliability must be at least as high as the validitycoefficient. Secondly, each validitycoefficient should be larger than all different-trait, different-method coefficients in the same row or column; among such comparisons, 314 of 364 (86.3 per cent) meet this test. Thirdly, each validitycoefficient should be larger than the different-trait, same method coefficients involving the same variable; 272 of 364 comparisons (74.7 per cent) meet this test. The resulting correlation would be a concurrent validitycoefficient. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.

For example, a validitycoefficient of.30 corresponds to 9 percent of variance explained. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The correlation between test scores and a measure of some criterion is called the "validitycoefficient". From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Under this definition, one can show that reliability of the test and the criterion places an upper limit on the possible correlation between them (the so-called validitycoefficient). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Validity coefficients are provided separately for both the alcoholic men and their wives. In this matrix, seven of the fourteen coefficients are significant at the 0.05 level; thirteen of the fourteen validity coefficients have the correct sign. First, the validity coefficients (different measures of the same variable) should be significantly greater than zero. While inductive methods select items based upon factor loadings, empirical items are selected based upon validity coefficients and their ability to accurately predict group membership.
