Want a quick summary of area from your dataset within ArcMap? Use the Statistics option while the attribute table is open.
1) Open your Attribute table if it isn't already open. Right-click on the theme's name and choose 'open attribute table'. The attribute table will open.
2) Right-click on the field in which to calculate statistics. Click on Statistics.
3) A Statistics window will appear outlining a summary of that field. This is useful when in need of a quick count, a sum, etc.
Things to keep in mind:
- If there are selected records, the statistics will be based on the selection.
- You must perform this on a numeric field.
