Summary functions available in a PivotTable list
The following table lists the summary functions provided by the AutoCalc 
command that you use to create total fields.
| Function | Description |
|---|---|
| Sum | Calculates the sum of the values. |
| Count | Tallies the number of values. Empty values, such as zero-length strings (strings that contain no characters), are included in the count, but null values (values that indicate missing or unknown data) are not included. |
| Min | Returns the smallest value in the field being summarized. |
| Max | Returns the largest value in the field being summarized. |
| Average | Returns the average of the values in the field being summarized. |
| Standard Deviation | Returns the standard deviation of the values in the field being summarized, assuming the values are a sample of a larger population. |
| Standard Deviation Population | Returns the standard deviation of the values in the field being summarized, assuming the values are the entire population. |
| Variance | Returns the variance of the values in the field being summarized, assuming the values are a sample of a larger population. |
| Variance Population | Returns the variance of the values in the field being summarized, assuming the values are the entire population. |
Note The summary functions available for a field depend on the type of data in the field. For example, if a field contains text, you cannot use Sum, Min, or Max, but you can use Count for that field.
