Percentile rank is the same as which concept?

• A. Mean.
• B. Proportion.
• C. Standard deviation.
• D. Cumulative percentage.

Answer: (D)

Percentile rank tells you where a score sits relative to the rest of the distribution by indicating the percentage of observations at or below that score. That idea matches cumulative percentage, which is the running total of percentages up to a given point in an ordered distribution. So if a score is at the 80th percentile, 80% of scores are at or below it, which is the same as the cumulative percentage up to that value. This differs from the mean (the average), the standard deviation (how spread out the scores are), or a simple proportion (a part of the total not tied to order).
