The information in this article applies to:

SUMMARY

The following is a worksheet function to provide an average of a range without the highest or lowest values:

   =( SUM(range)-MAX(range)-MIN(range) ) / (COUNT(range)-2)

Note that the parentheses are critical so that the function is computed in the right order.

The following is the same function as above, incorporated into a function macro:

   A1:  HILOAVERAGE
   A2:  =RESULT(1)
   A3:  =ARGUMENT("range",8)
   A4:  =(SUM(range)-MAX(range)-MIN(range))/(COUNT(range)-2)
   A5:  =RETURN(A4)

Note: You must define the macro on the macro sheet, then use a full pathname to the macro sheet on the worksheet. For example:

   =Macro1.xls!HILOAVERAGRE(A1:A8)

By choosing Formula Paste Function, you can paste this function in automatically.
