In the Statistic Analysis group on the Property Sheet tab and the Statistic Analysis group in the Context Menu of the property sheet, Seven functions of Statistic Analysis for the attribute table of Vector Dataset and Tabular Dataset are organized, including sum, average, maximum value, minimum value, variance, standard deviation and Count of Single Values.
| Statistic Analysis type | Description |
| Sum | It is used to count the sum of the attribute values of the selected fields in the attribute table. |
| Average value | It is used to count the average value of the attribute value of the selected field in the attribute table. |
| Maximum value | It is used to count the maximum attribute value in the selected field in the attribute table. |
| Minimum value | Used to count the lowest attribute value in the selected field in the attribute table. |

- The
- numerical field supports the above seven Statistic Analysis types;
- Boolean type, text type, Long Binary, character type field, only supporting statistical Count of Single Values;
- Date fields support statistical maximum, minimum, and Count of Single Values.
