BlakeQuartiles are values that divide a dataset into four equal parts, each containing 25% of the data. There are three quartiles: Q1, Q2 (also known as the median), and Q3. Q1 represents the 25th percentile, Q2 the 50th percentile, and Q3 the 75th percentile of the data. Quartiles are useful for understanding the spread and distribution of a dataset.
