Adding function fields to output layers

When you use Aggregate Attributes, Dissolve, or Statistical Overlay, you can add statistic and function fields to the output layer Attribute Table, or both.

You can add fields using the simple or advanced methods. With the simple method, you can add only one new field per attribute. With the advanced method, you can add several fields per attribute.

The statistic fields, Mean, Minimum, Maximum, Mode, Median, and Standard Deviation, are described in Setting a selected record statistics display.

Choose one of the following methods:
- To add fields using the simple method, click in an attribute cell in the Function column, and choose a function or statistic.
- To add fields using the advanced method, Click Advanced and click in a column for the attribute.
A check mark indicates the selected functions and statistics.
If you want to calculate the weighted average, click in the Weighted Avg column next to the attribute that you want to use in the calculation and choose an attribute.
