The percentile rank of a particular score is defined as the percentage of the scores in a distribution which are at or below the particular score. It is possible to determine some percentile ranks directly from the frequency distribution table, provided that the percentile ranks are percentages that appear in the table.hen a score is identified by its percentile rank, the score is called a percentile. It is also possible to determine some percentiles directly from the frequency distribution table, provided that the percentiles are upper real limits of a category.
