Variable # Cols Used for Avg & Range Calculation

[rwmill9716]

I need formula for Cols A & B that allow me to specify in cell F4 the number of columns that are to be used in the row calculation of average (col A) and Range (Col B as Max() - Min()). That is, I want to be able to change cell F4 from 2 to 20 and get the appropriate row averages in Cols A and B. For example, Cell A7 when F4=5 would calculate: Average(C7:G7); and Cell B7 would calculate: Max(C7:G7)-Min(C7:G7).

Thanks,

Try these array formulas entered with CTRL + SHIFT + ENTER

A7: =AVERAGE(IF(C$6:V$6<=$F$4,C7:V7))
B7: =MAX(IF(C$6:V$6<=$F$4,C7:V7))-MIN(IF(C$6:V$6<=$F$4,C7:V7))
