Which test uses a mean of 50 and standard deviation of 10 for its T-scores, as indicated in the material?

• A. PAI
• B. DASS-21
• C. K-10
• D. SDQ

Answer: (A)

T-scores standardize raw scores so that most people cluster around a mean of 50 with a standard deviation of 10, making it easy to see how far someone is from average in standardized units. The Personality Assessment Inventory uses this convention for its clinical scales, presenting scores as T-scores with mean 50 and SD 10. That specific scoring approach is what identifies it here. The other measures use different scoring methods: for example, DASS-21, K-10, and SDQ rely on raw totals or other non–50/10 standardized formats, so they don’t follow the same T-score convention.
