The summary statistics command can be used in arcpy to calculate statistics - this tool runs against a single field, eg:
SUM—Adds the total value for the specified field.
Is there an out-of-the-box method to calculate statistics across multiple fields?
eg I'd like to calculate the MIN, MAX, MEAN and STDEV of Field1, Field2 and Field3, combined:
OID Field1 Field2 Field3 Field4 1 23 24 25 26 2 12 13 14 15 3 17 18 19 20
One approach is to read through the table with a cursor, and calculate these values manually in a script. Is there a better/faster way?
Edit: I need this to run on only the selected records, and these will change frequently.
