Formula help...

[RTE]

I'm trying to create a formula that that returns an average value if two conditions are met. No luck here.

I need to be able to get to - Brand = Blue; Value = 2; X Count = average - from the following information. The average is 17.5

Thanks for your help.

 

[Brian from Maui]

Entered with CTRL + SHIFT + ENTER

=AVERAGE(IF(B1:B10="blue",IF(C1:C10=2,D1:D10)))

 

[Sal Paradise]

I get 16.5 as the average, but here's the formula without an array formula:

Excel Workbook
	A	B	C	D	E
1	Brand	Value	X Count	Y Count	Z Count
2	Green	1	21	31	52
3	Green	1	40	55	95
4	Blue	3	10	76	86
5	Red	1	16	49	65

Sal,

That is more expensive that Brian's proposal.

 

[Sal Paradise]

In all cases? I know that it's calculating a SUMPRODUCT twice, but I was under the (perhaps mistaken) understanding that SUMPRODUCT tends to be faster than array formulas over larger ranges. Or is it just an array formula in disguise?

SumProduct is designed to operate on array objects, hence no CSE. Here it gets expensive specifically because of "computing the same thing twice".

 

[Sal Paradise]

If operated on a range of 1000 rows, would it still be slower? 10,000 rows? Is SUMPRODUCT() just as slow as an array formula, only it seems faster because of the lack of {} around it?

Larger ranges affect the temporal profile adversely of almost all formulas, including specifically array and SumProduct formulas...

In the case under consideration, I expect

{=AVERAGE(IF(X="blue",IF(Y=2,Z)))}

to be faster than:

=SUMPRODUCT((X="Blue")*(Y=2),Z)/SUMPRODUCT((X="Blue")*(Y=2))

 

[Sal Paradise]

Thank you for the pointers.

SUMPRODUCT() is an array formula and the only difference is that it does not have to confirmed by CSE. The speed or the time taken to calculate when an array formula is implemented (irrespective of whether it is SUMPRODUCT() or any other array formula) over large ranges is pathetic unless you are using Excel 2007.

SUMPRODUCT() does not seem faster and neither it is faster then its counterparts. It is just that Excel provides the user a built-in array formula so that the user does not have to CSE everytime he enters or edits the formula.
