The Standard Distance and Directional Distribution tools

The Standard Distance tool measures the degree to which features are concentrated or dispersed around the geometric mean center. It shows the concentration or dispersal of data. The output circle created by this tool is defined by standard deviation and can include one, two, or three standard deviations. In general, the larger the circle, the more dispersed the data.

The Directional Distribution (Standard Deviational Ellipse) tool creates standard deviation ellipses to summarize the spatial characteristics of geographic features, including central tendency, dispersion, and directional trends. The ellipses are centered on the mean center. This tool calculates directionality, centrality, and dispersion.

In this exercise, you'll learn how to use both tools.
