The Crosstab tool automatically sorts headers and groups in what order?
Ascending
What does the Transpose tool do?
Moves values held in multiple horizontal columns into a single column
What does the Summarize tool do?
It can perform a host of summary calculations, including summing, min and max, grouping, counting, string concatenating, math, spatial object processing, and much more
