Linking and Equating Terminology: Raw Score and Rasch
TermLinn & Mislevy (Classical Test Theory) meaningRasch meaning
Linkinggeneral term for making the results of different tests comparableenabling the data to be analyzed together in one analysis (if desired) to construct one overall set of measures
Equatingcorrespondence of raw scores between testsputting the measures in the same frame of reference
Calibrationputting the scores in the same frame of referenceconstructing item measures in the internal frame of reference
Projectionscores on one test weakly predict scores on another test(a height-weight situation)
Moderationequivalences based on matching up sample statistics(Fahrenheit-Celsius equating)
Anchoring (fixing)-measures obtained from one analysis (or construct theory) imposed on another to place it in the same frame of reference.
Local originzero score or sample meanreference location from which to measure along the latent variable
