The Average by group step calculates the average of all values in one or more columns. This step is similar to the AVERAGEIF function in Excel.

Default settings

When a data source is first connected, this step will auto-select a numeric column (like ‘Quantity Sold’) and a data-type column to take a first pass at averaging by group.

Custom settings

You may choose any column to average, and group the average according to any one column, or multiple columns, in your data set.

You can optionally apply this to only the selected columns or apply to ‘all columns except’. We’d recommend using the option that requires fewer column selections to save yourself time.
