Quantile classification is a method used in thematic mapping to categorize data values into equal-sized groups, or quantiles, based on their distribution. This technique allows for the visualization of data that reflects how values compare relative to one another within a dataset, often making it easier to identify patterns and trends in geographic information. By dividing the data into classes that each contain the same number of observations, it highlights the relative ranking of values rather than focusing solely on their absolute magnitudes.
