WebReliability: The RSE demonstrates a Guttman scale coefficient of reproducibility of .92, indicating excellent internal consistency. Test-retest reliability over a period of 2 weeks reveals correlations of .85 and .88, indicating excellent stability. Validity: Demonstrates concurrent, predictiv e and construct validity using known groups. WebGuttman published six measures of reliability based on the split-half method. We will consider his lambda 4 measurement, namely. where h 1 represents the partial scores from the first half, h 2 represents the partial …
WebAug 2, 2024 · The average-eigenvalue test (Kaiser-Guttman test) retains the eigenvalues that exceed the average eigenvalue. For a p x p correlation matrix, the sum of the eigenvalues is p, so the average value of the eigenvalues is 1.
