What does percentile rank indicate?

• A. The score is higher than a given percentage of the reference population (e.g., 75th percentile means higher than 75%).
• B. The score is exactly equal to the mean.
• C. The score is in the top 5 percent only.
• D. The score is the average of the population.

Answer: (D)

Percentile rank shows where a score sits in a distribution by indicating the portion of the reference group that scored below it. So, a score at the 75th percentile means it’s higher than about 75% of the people in that group, and about 25% scored higher. This isn’t about the average or mean, which is a single central value. It also isn’t limited to being in the top 5 percent; that would correspond to a percentile around 95 or higher. Percentile ranks can describe any position from the 1st to the 99th percentile, reflecting relative standing within the distribution.
