C)writing clear instructions
D)ensuring the concurrent validity

Question

Quizplus · Accepted Answer

Alpha reliability, or Cronbach's alpha, is a measure of the internal consistency of a test or scale, indicating how closely related a set of items are as a group. It is improved by strategies that enhance the homogeneity and clarity of the items, such as adding more items (A), avoiding ambiguous items (B), and writing clear instructions (C). Ensuring the concurrent validity (D) relates to how well a test correlates with a measure of the same construct taken at the same time, which does not directly affect the internal consistency or alpha reliability of a measure.
