Internal consistency, which addresses the homogeneity of a single test form, may be assessed by correlating performance on two halves of a test, which is termed split-half reliability; the value of this Pearson product-moment correlation coefficient for two half-tests is adjusted with the Spearman–Brown prediction formula to correspond to the correlation between two full-length tests. [13], Psychometricians have also developed methods for working with large matrices of correlations and covariances. { bidder: 'openx', params: { unit: '539971066', delDomain: 'idm-d.openx.net' }}, { bidder: 'sovrn', params: { tagid: '346698' }}, These include classical test theory (CTT) and item response theory (IRT). { bidder: 'sovrn', params: { tagid: '387232' }}, "login": { Psychology Definition of PSYCHOMETRIC: An adjective based on psychometric characteristics.
