best way to find max and average values for data that meets certain criteria
I have a table with names in column B and dates in row 1. The rest of the tables is the sales amount for the employee listed in column B on the date in row 1.
I want to find the max and the average for certain days. For example we have 12 sales on various days a quarter. I want to be able to find the max sales amount on days days that we had sales, and the days we didn't have sales as well as the averages sales amount on the days we had sales and the days we didn't have sales.
I can find the row that the data is in using match: =MATCH(A2,data!B:B,0) I can find the if is a sale using max and maxifs in an arrary: {=MAX(MAXIFS(data!$C2:$N2,data!$C$1:$N$1,report!$M$1:$P$1))} or using =AGGREGATE(14,4,MAXIFS(data!$C2:$N2,data!$C$1:$N$1,report!$M$1:$P$1),1)
There is a problem with finding the max if it is not a sale. I am not sure why. I tried: =AGGREGATE(14,4,MAXIFS(data!$C2:$N2,data!$C$1:$N$1,"<>"&report!$M$1:$P$1),1) & {=MAX(MAXIFS(data!$C2:$N2,data!$C$1:$N$1,"<>"&report!$M$1:$P$1))}
I can find the average if it is a sale if there is data for every day, but not if there is data missing. Then I get a #DIV/0 error.
Any ideas on this?
E2 had to be:
=SUMPRODUCT(IFERROR((COUNTIF($H$1:$S$1,data!$C$1:$CF$1)=0)*
INDEX(data!$C$2:$CF$65,MATCH($A2,data!$B$2:$B$65,0),0),0)/
SUMPRODUCT((COUNTIF($H$1:$S$1,data!$C$1:$CF$1)=0)*
(INDEX(data!$C$2:$CF$65,MATCH($A2,data!$B$2:$B$65,0),0)<>"")))I got it to work!!! Thank you everyone for all of the help!!

If your definition of best is "the shortest", I will recommend this formula in C2, as shown in the snapshot below:
Delving into the attached file, you'll see this formula in G2:
=SUMPRODUCT(COUNTIF($M$1:$P$1,data!$C$1:$N$1)*
INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0))/
SUMPRODUCT(COUNTIF($M$1:$P$1,data!$C$1:$N$1*
(INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0)<>"")))Note that I used the elegant COUNTIF instead of the familiar ISNUMBER-MATCH combination.
- By admitting that my recommended formulas return your expected results, you must be contented thereby. Nonetheless, I admire your quest for a shorter formula but I deem my recommendation as heretofore the shortest!
The group of AVERAGE/IF/S cannot process array formulas! The most powerful among their “relatives” is the elegant COUNTIF, as you can prove in the file I attached earlier.
As variant
Max If Sale
=AGGREGATE(14,6,1/--ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0),1)Max If Not Sale
=AGGREGATE(14,6,1/--NOT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0)))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0),1)Average if sale
=SUMPRODUCT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0))/SUMPRODUCT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0))*(INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0)<>0))Average if Not Sale
=SUMPRODUCT(NOT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0)))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0))/SUMPRODUCT(--NOT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0)))*(INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0)<>0))I don't know if you know this or not. Why does aggregate work with Large but not max, average or count. I know the difference between Large(,) and Max() bit it doesn't see like that should be applying here.
AGGREGATE() works with array formulas as references starting from function #14 (Large) and next one. Previous functions work with arrays themselves.
Your methods work. I ended up going:
=MAX(--ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0),1)
=MAX(--NOT(ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0)))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0),1)
For the max of sales and not sales respectively.
What I do not understand is why if I try to do the same thing for average:
=AVERAGE(--ISNUMBER(MATCH(data!$C$1:$N$1,$M$1:$P$1,0))*INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),0),1)
It doesn't work. Why doesn't it?
I guess with MAX() instead of AGGREGATE() you use array formula which is not needed in latest case.
AVERAGE() doesn't work since using ISNUMBER() you add to the array zeroes for the values where condition is not met (in addition to zero sales) and average with these zeroes. Plus ,1 at the end of the formula is not needed.
You may try this...
In C2
=MAX(MAXIFS(INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),),data!$C$1:$N$1,report!$M$1:$P$1))In D2
=MAX(MAXIFS(INDEX(data!$C$2:$N$13,MATCH($A2,data!$B$2:$B$13,0),),data!$C$1:$N$1,"<>"&report!$M$1:$P$1))The one for C2 worked perfectly, but the one for D2 did not. The "<>"& doesn't give an error but it doesn't seem to be working. You are doing it they way I wanted to do it. I wasn't sure how to do an index match with maxifs, but it is working. Why does the <> work with an array?
Anyone know the answer to this?
