For example, a formula such as `AVG(SUM(x))` will produce an error.\n| **Note:** This function can be applied in one of the following ways:\n|\n| - In a data source, change a field's Aggregation to `Average`.\n| - In a report, [edit the field's aggregation](/looker/docs/studio/edit-fields-in-your-reports) in a chart.\n\nExamples\n--------\n\nIn these examples, the parameters passed to `AVG` are unaggregated numeric dimensions (i.e., they have an **Aggregation** type of **None** ).\n\nRelated resources\n-----------------\n\n- [Calculated fields](/looker/docs/studio/about-calculated-fields)\n- [Looker Studio function list](/looker/docs/studio/function-list)"]]
