Which statement best describes a power test relative to a speed test?

• A. All items must be answered within a short time.
• B. Items vary in difficulty, and credit increases for more difficult items.
• C. Items are crafted to measure rapid guessing.
• D. Scoring is based only on the number of items attempted.

Answer: (B)

Power tests measure what a person can do at increasingly difficult levels, with scoring that rewards correct answers on harder items. The idea is to push performance and give more credit for tackling and solving tougher questions, which is exactly captured by the statement that items vary in difficulty and credit increases for more difficult items. This differs from a speed test, where the focus is on answering quickly within a time limit, often with limited emphasis on item difficulty or the value of harder items. The other options don’t fit because they describe scenarios centered on rushing through items, guessing rapidly, or counting just the number of items attempted, none of which align with rewarding higher-difficulty performance in a power test.
