Hi.

I'm looking for a way to compute the average while excluding outliers. This average is based on 5 attribute values for each record. 

To expand, i am QCing pole counts within permits. Each permit is a record. There are a bit over 10k records. I have 5 attributes, with pole counts, each coming from a different source.

Example:

permit a, pole counts = 1, 4, 5, 28, 6

permit b, pole counts = 2, 10, 14, 80, 12

Manually, for permit a, i'd exclude 1 and 28 and my avg would be 5. For permit b, i'd exclude 2 and 80 and my avg would be 12. 

The final goal for this exercise is to pick the value closest to the average computed without outliers. 

Pls help. Thank you.

On what logic would you remove the outliers? Highest and lowest value? Standard deviation?

Assuming you’ve got as far as a single feature with all 5 counts in a single attribute separated by commas and you want to exclude lowest and highest and then get an average of the 3 remaining

Highest and lowest in this case.
