Question

The descriptive statistics based on test scores of representative groups of individuals is called:

• A. Z-scores
• B. Norms
• C. Reference Statistics
• D. Standard Scores

Answer 1

The Correct Option is B, D

Norms are statistical standards established by administering a test to a large, representative sample. They facilitate comparing an individual's test score to a reference group, offering context for score interpretation.

• For example, a test-taker's percentile rank or standard deviation relative to the norm group helps assess performance.
