   Question

   For passing the theory driving exam, some learning styles are more successful than others. In research on the influence of learning styles on exam results, a separate test has been developed for each learning style. Two test developers talk to each other about the meaning of measurement error $E$ within classical test theory.

   Evaluate the following two statements:

   I. The measurement error E of a test does not correlate ($r_{ET} = 0$) with the true score $T$. II. Between the measurement errors $E$ of the tests for the different learning styles is not consistent.

   
   
   1. TRUE: Pronunciation I and II are both correct.
   2. FALSE: Only pronunciation I is correct.
   3. FALSE: Only pronunciation II is correct.
   4. FALSE: Pronunciation I and II are both incorrect.
   
   

   Solution

   Theorem 1: According to classical test theory, measurement error is $E$ independent of the true score $T$, because $E$ is an accidental and unsystematic measurement error.

   Theorem 2: Measurement error $E$ is accidental and unsystematic; there is no consistency among them.
