Question

Quizplus · Accepted Answer

Measuring something important is the best choice to increase the reliability of a personality test. This means selecting items that are relevant and meaningful to the construct being measured. Aggregating items can also improve reliability, but refusing to aggregate items (choice A) would not necessarily increase reliability. Using very few items (choice C) increases the risk of mistakes and reduces the validity of the test. Constructing items with complicated words and phrases (choice D) can actually decrease the reliability of the test by introducing unnecessary confusion and ambiguity.
