If this property is set to null, all values are assumed to have weight one.
This property allows you to calculate weighted averages and totals. For example, if the data contains a 'Quantity' field and a 'Price' field, you could use the 'Price' field as a value field and the 'Quantity' field as a weight. The output would contain a weighted average of the data.
