Question

Quizplus · Accepted Answer

The major disadvantage of the coefficient of stability and equivalence is obtaining the two forms of the test. This can be time-consuming and expensive, especially in cases where the test needs to be administered multiple times. The other options listed (A, C, D, and E) are potential challenges in establishing reliability, but they are not specific disadvantages of the coefficient of stability and equivalence.
