Computing the average of the data values

You can build an expression by using the expression editor. For example, you can build an expression that computes the average of the values in the de_Runtime field.

To compute the average of the data values:

1. In the Expression dialog, expand Common Functions.
2. Under Common Functions, select Aggregate.
3. Under Item, double-click the Avg function to add it to the expression editor.
4. In the Categories pane, select the Fields category. The available data fields are displayed in the Fields pane.
5. In the Fields pane, double-click the de_Runtime field to add it to the expression editor.
6. Add a closing parenthesis ‘)' to complete the expression.
   For example,

   =Avg(Fields!de_RunTime.Value)

7. Click OK to transfer the expression to the cell.
