I used the quantile classification method to group my data under different ranks. I need to document which statistical method the software uses to calculate the quantiles.&nbsp;</P><P>Many thanks.&nbsp;</P> Thu, 15 Feb 2024 16:40:48 GMT https://community.esri.com/t5/arcgis-pro-questions/quantile-classification-method/m-p/1382899#M78856 Shadim 2024-02-15T16:40:48Z https://community.esri.com/t5/arcgis-pro-questions/quantile-classification-method/m-p/1382932#M78862 <P>For categorical data (observations, counts, features etc)</P><P><A href="https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/data-classification-methods.htm" target="_blank">Data classification methods—ArcGIS Pro | Documentation</A></P><P>For interval/ratio data, the frequency distribution would be used to determine the 5 20% bounds</P> Thu, 15 Feb 2024 17:23:19 GMT https://community.esri.com/t5/arcgis-pro-questions/quantile-classification-method/m-p/1382932#M78862 DanPatterson 2024-02-15T17:23:19Z
