Classification Types

When you classify feature data, classification method and the number of classes you specify greatly affects how a theme is displayed and interpreted.
In the examples below, notice how the theme's display changes when the Pop_93 field values are grouped into five classes using different classification methods. The features have been grouped with the Natural Breaks, Equal Area (the area they occupy), Standard Deviation, Equal Interval (the interval between classes), and the Quantile (quantity of features in each class) classification methods.
