An illustrative example of a performance test item is provided beneath. Reliability coefficients theoretically range in worth from zero (no reliability) to 1.00 (perfect reliability). In apply, their approximate range is from .50 to .ninety for about 95% of the classroom exams scored by ScorePak®.

Much Like Forms Of Take A Look At Objects

These objects comprise components of the Tests which are used to assess Test-taker efficiency. Whereas the reliability of a check at all times varies between zero.00 and 1.00, the standard error of measurement is expressed in the same scale as the test scores.
