- The first quartile, or 25th percentile x L (also written as Q 1), is the number for which 25% of values in the data set are smaller than x L. The second quartile or 50th percentile, x m (also written as Q 2) is also known as the median. It represents the value for which 50% of observations are lower and 50% are higher. The third quartile or 75th percentile, x H (Q 3) is the value such that 75%
