In The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics, Mitchell (the author) takes users deeper, showing how an emerging set of tools that rely on spatial statistics provides GIS users the capability to conduct detailed, mathematical analysis of geographic information, This second volume introduces statistical tools, geared specifically for geographic analysis, that are relatively new to GIS software packages and thus to most GIS users. It shows the tools in use in many different applications, explains which tools are best with which situations, and provides guidance on interpreting the results you get. The ESRI Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics focuses on four fundamental tasks of statistical analysis. These are: calculating the center, dispersion, and trend, Identifying patterns, Identifying clusters and Analyzing geographic relationships.
