For example, the 97th percentile (P97) is the value such that 97% of the data points are less than it. Percentiles are a type of quantiles, obtained by a subdivision into 100 groups. The 25th percentile (P25) is also known as the first quartile (Q1), the 50th percentile (P50) as the median or second quartile (Q2), and the 75th percentile (P75) as the third quartile (Q3). For example, the 50th percentile (median) is the score below (or at or below, depending on the definition) which 50% of the scores in the distribution are found.
