... Bias usually favors one group of test takers over another. Calibration The process of setting a test score scale, including the mean, stanciarc3 deviation, and possibly the shape of the score distribution, so that scores on the scale have the same relative meaning as scores on a relatecl score scale.

... ranges from 1.0, signifying perfect agreement, through 0.0, representing no agreement at all, to -~.0, representing perfect negative agreement, with high scores on one variable associated with low scores on the other. Criterion referenced test A test that allows users to estimate the amount of a specified content domain that an incliviclual has learned.

... Distribution The number, or the percentage, of cases having each possible data value on a scale of data values. (In testing, data values are usually test scores.)

... Matrix sampling A measurement format in which a large set of test items is organized into a number of relatively short item sets, each of which is randomly assigned to a subsample of test takers, thereby avoiding the need to administer all items to all examiners. Mean The numerical average of a set of data values, such as test scores.

... The term "normal" is used to connote customary, or related to the norm, not ideal. Normalized standard score A clerivec3 test score in which a numerical transformation has been chosen so that the score distribution closely approximates a normal distribution for some specific population.

From page 109...
... Reference population The population of test takers represented by test norms. The sample on which the test norms are based is intended to permit accurate estimation of the test score distribution for the reference population.

From page 110...
... In classical test theory, the term represents the ratio of true score variance to observed score variance for a particular examiner population. The conditions uncler which the coefficient is estimated may involve variation in test forms, measurement occasions, raters, or scorers, anc3 may entail multiple examiner products or performances.

... Selected response item Test item for which test taker selects response from proviclec3 choices; also known as multiple~choice item. Social moderation An adjustment in the values of test scores to adjust for known social factors affecting test scores for a group of test takers.

... See also social moderatior~. Systematic error A score component (often observed indirectly, not related to the test performance, that appears to be related to some salient variable or subgrouping of cases in an analysis.
