Passage

Read the following passage and answer the questions that follow:

The Classical Test Theory (CTT) assumes that every obtained score is a sum of the true score and the error of measurement. The earlier versions of the CTT, in their reliability conceptualization, ambitiously addressed the random errors of measurement. Accordingly, reliability can be conceptualized as a consistency between the true score and the obtained score. Reliability can be studied through various perspectives. In the test construcion phase, internal consistency reliability is given heavy emphasis. Various reliability co-efficients such as Kuder-Richardson reliability, Cronbach alpha, etc. have been developed for this purpose. One of the earlier developments in CTT is the Spearman-Brown Formula. The other important types of reliabilities include test-retest reliability and interscorer reliability.

In addition to reliability, psychologists emphasize test validity. Content validity, concurrent validity, predictive validity, construct validity are some of the important types of validities in psychometric studies. Factor analysis has also been employed in evaluating the test validity. Once the reliability and validity are well established, the test constructor attempts to establish the representative and comprehensive norms.
