I'm trying to average the most recent 6 values of 'x' - however, I'm getting reference errors when trying to average them. The value I'm looking for should be 8,720.33 with the criteria of 'x'. The dates have no bearing in the formula, just a visual reference point.
Formula I'm getting lost on "=AVERAGE(OFFSET(INDEX(C2:C42,MATCH(E2,B2:B42,0),),0,0,-6))"
*Note - the dates are being updated daily to include historical data points
Data Set:
You can try following array formula:
=AVERAGE(INDEX(C1:C25,N(IF(1,AGGREGATE(14,6,ROW(A1:A25)/(B1:B25=E2),ROW(A1:A6)),0))))
or with full ranges:
=AVERAGE(INDEX(C:C,N(IF(1,AGGREGATE(14,6,ROW(A:A)/(B:B=E2),ROW(A1:A6)),0))))
Confirm it with ctrl + shift + enter
You might be able to pull this off with AVERAGEIFS if you add a rank column that ranks Header1 by date.
In my example:
Column D is the Values you are averaging
Column B is Hearder1
Column C is the rank - =COUNTIFS($B:$B,B2,$A:$A,">"&A2)+1
=AVERAGEIFS($D:$D, $B:$B, "x", $C:$C, "<7")

The excel file contains a structure table. (which I find difficult to work with but I can't alter the file structure, I am just adding a summary tab with various counts from the data table.)
Item
Month
1
2
2
2
2
2
2
3
3
3
3
4
The item number itself can repeat and be repeated within the same month.
I was able to get a count of total number of unique items using this formula.
=SUMPRODUCT((Item_tab[Item]<>"")/COUNTIF(Item_tab[Item],Item_tab[Item]&""))
Looking for how to count the number of unique items within a specific month.?
Example of Desired output.
Edit/Set formula for Month 2 , output should be 2
Edit/Set formula for Month 3 , output should be 2
Edit/Set formula for Month 4 , output should be 1
I cannot figure out how to apply countifs to something that needs to avoid duplicates in multiple columns.
Tried this but returns #VALUE!
=SUMPRODUCT((Item_tab[Item]<>"")/COUNTIFS(Item_tab[Item],Item_tab[Item]&"",'Item'!M:M,6))
The month column was added later and I don't know how why or how to get that column to have the structured table column Header like everything else.
The sheet name is Item
The Table Name is Item_tab
I can find where to rename the table but not the columns. Not sure the variance is causing an issue. The month column is absolutely part of the table in every way that I can see.
You can try the following in cell D2:
=LET(A, A2:A7, B, B2:B7, uxB, UNIQUE(B), cnts, BYROW(uxB, LAMBDA(u,
ROWS(UNIQUE(FILTER(A, B=u))))), HSTACK(uxB, cnts))
Here is the output:
If you want to get the result repeated instead of consolidating the result by unique months, you can try the following:
=LET(A, A2:A7, B, B2:B7, uxB, UNIQUE(B), BYROW(B, LAMBDA(u,
ROWS(UNIQUE(FILTER(A, B=u))))))
If you don't have such function available, you can try the following formula in D2, it produces the same result as the first formula:
=CHOOSE({1,2}, UNIQUE(B2:B7),
MMULT(N(MMULT(TRANSPOSE(N(B2:B7=TRANSPOSE(UNIQUE(B2:B7)))),
N(A2:A7=TRANSPOSE(UNIQUE(A2:A7))))>0), SEQUENCE(ROWS(UNIQUE(A2:A7)),,1,0)))
or using LET for a better reading and maintenance:
=LET(A, A2:A7, B, B2:B7, CHOOSE({1,2}, UNIQUE(B),
MMULT(N(MMULT(TRANSPOSE(N(B=TRANSPOSE(UNIQUE(B)))),
N(A=TRANSPOSE(UNIQUE(A))))>0), SEQUENCE(ROWS(UNIQUE(A)),,1,0))))
I have simple problem, but I've not be able to get an answer from searching. I require a column to calculate the number of the nth occurrence of a value. It's best explained in this picture
I require a method to calculate column B.
I'd be very grateful for any help.
Are you looking to merely provide a count of the distinct entries of column A in column B? Or merely add a formula to come up with the table in your link?
If the latter, then the formula to write in cell B2 is:
=COUNTIF(A$2:A2,A2)
then copy/paste it down column B. Note - if your data is both a Date and Time, but the cell is formatted to only display a date, you may not get the results you want. You'd need to interject a new column with a "floor" calculation to round the date/time value to a date (Excel date times are decimal, with integer part dictating the date, and remaining 0.0 -> 1.0 dictating the time of day)
If you just want to derive a table of the counts of distinct entries in column A, then a pivot table will do this for you - simple add a pivot table to cover the data in column A, then select column A into the rows category, and then also drag it into the values category, ensuring the field is set to "Count of". You should then have a table with the distinct entries in your data set in one column, and the count of their occurrences in the other column.
You can use the COUNTIF worksheet function, with a relative address.
Eg. In cell B2, enter this formula:
=COUNTIF(A$2:A2,A2)
And then fill-down.
Use the following formula to generate the required series:
=COUNTIF($A$1:A1,A1) and strech(copy) it in all the cells
This will generate result like this:
A 1 COUNTIF($A$1:A1,A1)
A 2 COUNTIF($A$1:A2,A2)
C 1 COUNTIF($A$1:A3,A3)
C 2 COUNTIF($A$1:A4,A4)
B 1 COUNTIF($A$1:A5,A5)
B 2 COUNTIF($A$1:A6,A6)
A 3 COUNTIF($A$1:A7,A7)
C 3 COUNTIF($A$1:A8,A8)
D 1 COUNTIF($A$1:A9,A9)
D 2 COUNTIF($A$1:A10,A10)
D 3 COUNTIF($A$1:A11,A11)
D 4 COUNTIF($A$1:A12,A12)

I have a table like the image given above. There is another sheet which reports some information based on this data. I need the sum of Apples in the last week for a given month.
The answer for apples for 8 th month would be 14 assuming there is another record as Apples - 32 - 10 - 8.
So I would have to find max week number for a given month and then sum the quantity for Apples with max week number
The formula written is
=SUMIFS( C2:C300, A2:A300, H16, B2:B300, MAX(IF(D2:D300=MONTH(TODAY()-1),B2:B300)))
H16 contains the word "Apples"
Column A - Item
Column B - Week
Column C - Quantity
Column D - Month
Column H - Unique Items again..
MAX(IF(D2:D300=MONTH(TODAY()-1),B2:B300)) returns the correct max as 32 for month 8 but the formula returns the value as 0. If I put the max formula in aseperate cell and refer that cell in main formula, it works as expected. I am not sure why the result of max value is not being used for sumif function.
Your formula is good. all you need to do is to convert it into Array Formula. Just type the formula with Ctr + shift + enter.
{=SUMIFS( C2:C300, A2:A300, H16, B2:B300, MAX(IF(D2:D300=MONTH(TODAY()-1),B2:B300)))}
Actually, without array, the part IF(D2:D300 evaluates to #value error as Excel doesn't not know how to compare an array against one value.
Hint: Not sureif you know it already, but anyways, always use Formulas --> Evaluate Formula to pin-point an error in a formula.
Hoping someone can help me with my trouble with an index/match formula.
Column B has a list of names, column C has the frequency of an action taken (sales made) whilst column D has the average sales value.
I've created in column G a track of the 6 highest sales which has worked great:
=LARGE($D$8:$D$13, 2)
Then I've used column F to determine the name that matches each sales average:
=INDEX($B$8:$B$13, MATCH(G4, $D$8:$D$13, 0))
So far so good! However, I'd like to only include the sales average if that individual has had more than 3 sales. IE; the value in column C is >3.
Can any one provide help or suggestions please?
I think you could use a helper column to filter out the values you don't need before applying =LARGE() in the very beginning, like this:
=IF($C8>3, $D8, "")
Then do =LARGE() to this column instead:
=LARGE($X$8:$X$13, 2)
You could use an array formula:
=LARGE(IF(range=criteria,values),n)
so for your case:
=LARGE(IF($C$8:$C$13>3,$D$8:$D$13), 2)
press CTRL+SHIFT+ENTER to enter an array formula.
