I am attempting to use an array formula with multiple criteria in an AVERAGEIFS formula.
=AVERAGEIFS('sheet1'!$R:$R,'sheet1'!$B:$B,{"a","b","c","d","e","f","g","h","i"},'sheet1'!$A:$A,Q$2)
The formula only seems to be calculating the first criteria that is within the array ("a").
I searched the forums, but I am not seeing anything that directly relates to this this.
Any and all help would be greatly appreciated!
The trick when using an array inside something like AVERAGEIFS is to then wrap it in AVERAGE. However, this will take the average of the averages which is probably not what you want. This method however does work well with Counts and Sums from which you can make your own average.
=SUM(SUMIFS(SumRange,CriteriaRange,{"a","b","c"}))/SUM(COUNTIFS(CriteriaRange,{"a","b","c"}))
This will be the same answer as if you had used Average(<select only the cells with "a", "b", "c" values>)
And to elaborate on how the Average(AverageIfs()) process works you can see the difference when you Evaluate your formula
There AverageIfs only regarded the first argument of the array.
However when it is returning a value to another function which itself can take an array as an argument the array is preserved

Looking to try and find the following in Excel but am having issues getting this to work.
I have Dates in Column A which need to be checked against Dates in the Query Column to compare. I want to count all records where the comparison column is greater than the date in A5 or is an empty cell. There are other conditions that I will also want to check but cannot seem to get this to work.
=COUNTIFS(Query1[Purchased Date],OR(Query1[Purchased Date]="",Query1[Purchased Date]>A5))
use:
=SUMPRODUCT(--((Query1[Purchased Date]="")+(Query1[Purchased Date]>A5)>0))
You can use an array function instead of countif.
Suppose your dates are in the range A2:A25 and your reference date is in cell B2.
If you type in any other cell
=SUM((A2:A25>B2)+(A2:A25=""))
and hit Ctrl+Shift+Enter it will give you the count you want.
This happens because Excel will resolve the first inner parentheses (A2:A25>B2) as an array of TRUE/FALSE, and does the same to the second (A2:A25=""). Next it will sum them, which is equivalent to the OR operation, and yields as a result an array of zeros (FALSE) and ones (TRUE). It wraps up by summing this array (with the function sum), all in one cell.
Perhaps this is more of a comment than an answer, but in this particular case you can just add the two separate totals:
=COUNTIF(Query1[Purchased Date],"")+COUNTIF(Query1[Purchased Date],">"&A5)
because the conditions are mutually exclusive.
Whether this helps or not depends on what additional criteria you want to add.
BTW there are two issues with your original formula:
(1) If you are combining lists of values with OR logic, you have to use addition instead (as in the two answers which use Sum or Sumproduct).
(2) The syntax of a Countif or Countifs where the range has to be kept separate from the criteria won't let you do what you want to do, so this again leads you to Sum or Sumproduct.
I have a question regarding COUNTIFS. The simple boiled down version of what I am trying to do is this:
I am trying to use COUNTIFS to count the number of entries that the cell in a column is either blank or in the future (greater than today) and that is marked with an “X” in another column.
There are several other renditions in the formula but if I can get this, I can get the rest. So far, I have this:
=SUM(COUNTIFS($C$2:$C$50,{"";">"&TODAY()},$E$2:$E$50,"X"))
Excel won’t let me return out of the formula and highlights the quotation mark following the greater than symbol.
=SUM(COUNTIFS($C$2:$C$50,{"";">100"},$E$2:$E$50,"X")) works fine when I play around and test things but when I try to add in &TODAY() or reference a cell, things go sideways.
Any suggestions as to what I am doing wrong? The actual formula is quite long and there are several comparisons that are made between columns. I've seen some references to using SUMPRODUCT but haven't been able to figure it out that way either.
You can use a formula to generate the criteria array, i.e.
=SUMPRODUCT(COUNTIFS($C$2:$C$50,IF({1;0},"",">"&TODAY()),$E$2:$E$50,"X"))
I used SUMPRODUCT in this version because with SUM you'd need CTRL+SHIFT+ENTER
The IF function generates an array that resolves to something like this:
{"";">43060"}
I am trying to produce a count of the number of times different strings come up in an Excel table. An example table, currently in SHEET1, would be this:
I have another table in another spreadsheet where I want to indicate, for each letter on the left in Table 1, how many entries for "za", "zc" or "zd" come up on the right. However, I would only like to only consider one entry of each.
The end result, on row B of SHEET2, would have to be something like this:
At the moment I am using a combination of SUM and COUNTIFS to do the job.
More specifically, applied to the example, I am using the following formula:
=SUM(COUNTIFS(Sheet1!A1:A18,Sheet2!$A1,Sheet1!B1:B18,{"za","zc","zd"}))
The formula is doing some of what is intended. However, it is not counting each entry just one time. Instead, its is counting, for each letter on the left, every entry of "za","zc" or "zd". The table that the formula is returning is as follows:
How can I change the formula so that it does what I intend?
Thank you.
My initial thought would be:
=SUM(MIN (1,COUNTIFS(Sheet1!A1:A18,Sheet2!$A1,Sheet1!B1:B18,{"za","zc","zd"}))
but I’m not where I can test if the MIN will apply properly to the COUNTIFS array of results. ;-)
EDITED: The MIN function is taking minimum of 1 or all of the items in the COUNTIFS array, rather than minimum of 1 and each item in the COUNTIFS array, which is what I was afraid of. Using
=MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"za"),1)+MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"zc"),1)+MIN(COUNTIFS(Sheet1!A$1:A$18,Sheet2!$A1,Sheet1!B$1:B$18,"zd"),1)
will gain the desired results. It is a little clunky, but simpler than an array formula. If you want an array formula, you can use:
=SUM(FREQUENCY(IFERROR(MATCH({"za","zc","zd"},(IF(Sheet1!$A$1:$A$18=$A5,Sheet1!$B$1:$B$18)),0),""),IFERROR(MATCH({"za","zc","zd"},(IF(Sheet1!$A$1:$A$18=$A5,Sheet1!$B$1:$B$18)),0),"")))
This uses the FREQUENCY function to take a set of values and see how many items in another set of values fall within each of the data ranges. Since you need text instead of numbers, we use the MATCH function to find out the first time the value occurs in your list, returning "" with the IFERROR function if it doesn't. (We only need the first occurrence since you don't want to know how many occurrences there are). Since it is text, we use the same input for both arguments for FREQUENCY.
Therefore, if you need to change the values you are looking for or the ranges in which you are searching, make sure to change both! Alternately, you could list the values out somewhere, say in F1:F3, and make a named range for this, another one for A1:A18, and another for B1:B18. Your formula would then look something like this:
=SUM(FREQUENCY(IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),""),IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),"")))
Then you need only change your named range definitions and your formulas would update. :-)
NOTE: Since this is an array formula, you must close out of the cell by pressing CTRL+SHIFT+ENTER rather than only ENTER. When you look at the formula bar, you should see
{=SUM(FREQUENCY(IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),""),IFERROR(MATCH(SearchValues,(IF(colA=$A2,colB)),0),"")))}
It does NOT work to enter the curly braces yourself. ;-)
You can use this formula at B1 and fill down:
B1:
=SUMPRODUCT(((Sheet1!$A$1:$A$18=A1)*(Sheet1!$B$1:$B$18= {"za","zc","zd"}))/
COUNTIFS(Sheet1!$A$1:$A$18,Sheet1!$A$1:$A$18,Sheet1!$B$1:$B$18,Sheet1!$B$1:$B$18))
=SUMIFS($B:$B*$N:$N,$N:$N,">=5",$N:$N,"<10")
I want to multiply 2 columns and sum all instances of it, conditioned only on one of the columns.The formula gives an error because I multiply in the first argument, which just should be a single number I guess. I tried using SUMPRODUCT too, but as column B does not have a condition, it doesn't work. Can anyone advice please. Thanks in advance.
The equivalent SUMPRODUCT formula for your SUMIFS attempt is:
=SUMPRODUCT(B:B,N:N,--(N:N>=5)*(N:N<10))
But you should avoid using full column references in SUMPRODUCT. If you can't limit range sizes, consider using dynamic named ranges.
try:
=SUMPRODUCT(B:B,IF(N:N>=5,IF(N:N<10,N:N,""),""))
with array ctrl+shift+enter
I need to use the Excel Indirect() function to reference a non-contiguous range. This (How to define a non continuous range in COUNTIF) answer gives an example.
In summary, the OP has two ranges, C1:C15 and A16. Each range contains either an A or a B, and the way to count the number of B's across these two ranges is
=SUM(COUNTIF(INDIRECT({"C1:C15","A16"}),"B"))
If I change all the B's to 1's and the A's to 0's, and change this formula slightly to
=SUM(COUNTIF(INDIRECT({"C1:C15","A16"}),"1"))
Then this still works ... BUT! this doesn't:
=SUM(INDIRECT({"C1:C15","A16"}))
I can work around this, but am I missing something fundamentally magic about the COUNTIF() function, that somehow influences the INDIRECT() function to behave as expected?
It's not possible to use a non-contiguous range in COUNTIF.
What's actually happening with the first formula is that COUNTIF is being fed with an array of (two) separate ranges and therefore the result is an array of the results of two counts, then SUM is used to sum the array.
If you actually have 1s and zeroes wouldn't you just SUM them with this formula
=SUM(C1:C15,A16)
If you are just trying to find why your last formula doesn't work then, yes, I think COUNTIF does work differently - it's able to handle an array of ranges while some other functions can't. This is common to the "IFS" family of functions, so SUMIF, for example, can do the same
