What Are Percentiles? Percentiles are measurements that show where a child is compared with others. On the growth charts, the percentiles are shown as lines drawn in curved patterns. When doctors plot a child's weight and height on the chart, they see which percentile line those measurements land on.
The percentile rank of a score is the percentage of scores in its frequency distribution that are equal to or lower than it. For example, a test score that is greater than or equal to 75% of the scores of people taking the test is said to be at the 75th percentile rank.ome percentile ranks are closer to some than others. Percentile rank 30 is closer on the bell curve to 40 than it is to 20. The mathematical formula is. where c â is the count of all scores less than the score of interest, Æ i is the frequency of the score of interest, and N is the number of examinees in the sample.
