How is a percentile rank defined in norm-referenced testing?

• A. The percentile rank is the percentage of the reference population scoring at or below a given score.
• B. The average of all scores in the reference population.
• C. The range of scores in the reference group.
• D. The probability of scoring above the mean.

Answer: (A)

In norm-referenced testing, percentile rank measures your position relative to a reference group. It is defined as the percentage of people in that reference population who score at or below a given score. For example, if you’re at the 70th percentile, 70% of the reference group scored at or below your score. This focuses on relative standing within the distribution, not on the test’s average (central tendency) or how wide the scores spread (range). It’s also not about the probability of scoring above the mean; that would describe a different, distribution-based idea.
