I've had a bit of trouble explaining this so please bear with me. I'm also very new to using excel so if there's a simple fix, I apologize in advance!
I have two columns, one listing number of days starting from 0 and increasing consecutively. The other column has the number of orders delivered. The two correspond to each other. For example, I've typed out how it would look below. It would mean that there were 100 orders delivered in 1 day, 150 orders delivered in 2 days, 800 orders delivered in 3 days, etc.
Is there a way to get summary statistics (mean, median, mode, upper and lower quartiles) for the number of days it took for the average order to get delivered? The only way I can think of solving this is to manually punch in "1" 100 times, "2" 150 times, etc. into a new column and take median, mean, and upper & lower quartile from that, but that seems extremely inefficient. Would I use a pivot table for this? Thank you in advance!
I tried using the data analysis add-on and doing summary statistics that way, but it didn't work. It just gave me the mean, median, mode, and quartiles of each individual column. It would have given me 3 for median number of days for delivery and 300 for median number of orders.
Method 1
The mean is just
=SUMPRODUCT(A2:A6,B2:B6)/SUM(B2:B6)
Mode is the value with highest frequency
=INDEX(A2:A6,MATCH(MAX(B2:B6),B2:B6,0))
The quartiles and median (or any other quantile by varying the value of p) from first principles following this reference
=LET(p,0.25,
values,A2:A6,
freq,B2:B6,
N,SUM(freq),
h,(N+1)*p,
floorh,FLOOR(h,1),
ceilh,CEILING(h,1),
frac,h-floorh,
cusum,SCAN(0,SEQUENCE(ROWS(values)),LAMBDA(a,c,IF(c=1,0,a+INDEX(freq,c-1)))),
xlower,XLOOKUP(floorh-1,cusum,values,,-1),
xupper,XLOOKUP(ceilh-1,cusum,values,,-1),
xlower+(xupper-xlower)*frac)
Method 2
If you don't like doing it this way, you can always expand the data like this:
=AVERAGE(XLOOKUP(SEQUENCE(SUM(B2:B6),1,0),SCAN(0,SEQUENCE(ROWS(A2:A6)),LAMBDA(a,c,IF(c=1,0,INDEX(B2:B6,c-1)+a))),A2:A6,,-1))
=MODE(XLOOKUP(SEQUENCE(SUM(B2:B6),1,0),SCAN(0,SEQUENCE(ROWS(A2:A6)),LAMBDA(a,c,IF(c=1,0,INDEX(B2:B6,c-1)+a))),A2:A6,,-1))
=QUARTILE.EXC(XLOOKUP(SEQUENCE(SUM(B2:B6),1,0),SCAN(0,SEQUENCE(ROWS(A2:A6)),LAMBDA(a,c,IF(c=1,0,INDEX(B2:B6,c-1)+a))),A2:A6,,-1),1)
=MEDIAN(XLOOKUP(SEQUENCE(SUM(B2:B6),1,0),SCAN(0,SEQUENCE(ROWS(A2:A6)),LAMBDA(a,c,IF(c=1,0,INDEX(B2:B6,c-1)+a))),A2:A6,,-1))
and
=QUARTILE.EXC(XLOOKUP(SEQUENCE(SUM(B2:B6),1,0),SCAN(0,SEQUENCE(ROWS(A2:A6)),LAMBDA(a,c,IF(c=1,0,INDEX(B2:B6,c-1)+a))),A2:A6,,-1),3)
So, the point is, in my dataset I have to create a variable "Moving Avg. Amt paid per sq. ft." and the formula or the logic I need is to calculate the last five values as per most recent transactions. i.e. most recent sales by date. but this average should only return value in case it matches the same building and same area variable.
This is what my data looks like
Area ID has three categories. Building number has 5 categories. Date is sorted in ascending order. Now my variable moving average should calculate last 5 averages w.r.t date but for the same building in the same area. e.g. there are buildings 1 and 2 in area 102. I need my Mov Avg. variable to calculate using conditions when it matches criteria of building 1 in 102 for past five sales and when it finds building 2 in the building number variable, it should calculate average of last 5 sales of that building in area 102.
So my approach to this issue was (which is flawed at the moment):
I calculate average of amount paid per sq. foot w.r.t area & building based on dates using the formula
=AVERAGEIFS($N$2:$N$6547,$D$2:$D$6547,D14,$C$2:$C$6547,C14,$B$2:$B$6547,B14)
but I cannot make this formula work, to calculate moving average whenever it meets the criteria. I tried the offset the point as well by 5 but the logic is not right and hence its not working and returning #value in the cells. The formula I used to offset the above condition is
=AVERAGEIFS((OFFSET(N13,5,,5)),$D$2:$D$6547,D13,$C$2:$C$6547,C13,$B$2:$B$6547,B13)
(These formulae are used in column Q of my data)
Need a support from the community as I am badly stuck in making this data useful and I am out of any ideas to make this work.
Edit 1: I am not sure how I can attach my excel file here so you may review the dataset. I have uploaded it on a third party site, for which the link is shared below, so you can view the file in detail.

Expected result is as I have mentioned the instruction said
"Create a variable called "mov. avg amt. paid per sq ft". For each row, this variable should calculate average amt paid per sq ft for the most recent past five sales (by date) for the same building in the same area."
And my approach to build a logic or formula to make this variable calculate moving average w.r.t date for same building in the same area doesn't seem to work because there might be some flaws.
In Office 365 you could use:
=LET(f,FILTER($N$1:N13,($B$1:B13=B14)*($C$1:C13=C14),""),
c,COUNTA(f),
s,SEQUENCE(5,,c-5),
IFERROR(IF(c<5,SUM(f)/c,SUM(INDEX(f,s))/5),""))
If there's less than 5 matches prior to the current sales it'll calculate the average of the count. If 5 or more matches it'll calculate the average of the last 5 prior to the current sale.
I do not want to know the traditional frequency or the traditional averages; so I'll give an example below:
I have this data:
1
3
5
5
2
3
5
5
1
3
The analysis that I would like to obtain is the following:
for example number 1 appears once every eight rows, number 3 appears once every four rows, number 5 appears twice every two rows....
I did it by hand, but now I have more than 21000 rows of data and I'm stuck.
I searched but I can not find a function that does it; But before I started developing my own, I decided to ask for a guide on how to achieve it.
I believe that I was able to achieve the desired result:
The formula is:
Or, if you want to copy/paste:
=IF(CONCATENATE("1-",MATCH(D1,INDIRECT(ADDRESS(MATCH(D1,A1:A17,0)+1,1,4)&":A17"),0))="1-1",CONCATENATE("2-",MATCH(D1,INDIRECT(ADDRESS(MATCH(D1,A1:A17,0)+2,1,4)&":A17"),0)-1),CONCATENATE("1-",MATCH(D1,INDIRECT(ADDRESS(MATCH(D1,A1:A17,0)+1,1,4)&":A17"),0)))
Note that the IF function solves the duplicates (like the number 5). In case you have triplicates you will have to add another instance of IF and adjust the formula accordingly.
Hope that helps!
Well this doesn't exactly reproduce your results, but you could start by looking at the max and min separation of the numbers:
=IF(COUNTIF(A$1:A$10,C2)<=1,"",MIN(IF((ROW(A$1:INDEX(A$1:A$10,COUNTIF(A$1:A$10,C2)+1))>1)
*(ROW(A$1:INDEX(A$1:A$10,COUNTIF(A$1:A$10,C2)+1))<=COUNTIF(A$1:A$10,C2)),
FREQUENCY(IF(A$1:A$10<>C2,ROW(A$1:A$10)),IF(A$1:A$10=C2,ROW(A$1:A$10)))))+1)
=IF(COUNTIF(A$1:A$10,C2)<=1,"",MAX(IF((ROW(A$1:INDEX(A$1:A$10,COUNTIF(A$1:A$10,C2)+1))>1)
*(ROW(A$1:INDEX(A$1:A$10,COUNTIF(A$1:A$10,C2)+1))<=COUNTIF(A$1:A$10,C2)),
FREQUENCY(IF(A$1:A$10<>C2,ROW(A$1:A$10)),IF(A$1:A$10=C2,ROW(A$1:A$10)))))+1)
This gives the min or max number of rows between each occurrence of the particular number.

You could add other statistics (like mean, standard deviation) the same way although the average could be calculated just by (lastrow-firstrow)/(count-1) e.g. for 5 it would be (8-3)/(4-1)=5/3.
I am trying to work out the average of scores for the male artists. When I tried using the AVERAGEIFs function it returned a #VALUE error and therefore I have created a table to work out the average manually. The expected score is 3.9 however when I use my table which adds up all the scores and then the number of scores which are not blank and divides the total score by number of scores the answer is 3.4.
Could you please advise on why this would be and if there is a way to calculate the average of male artists?
Here is an image of my spreadsheet:
To my knowledge, AVERAGEIFS() works on a single column / single row.
Thus, you need a helping row, showing you the AVERAGE per person, and then taking the average, with conditions such as Gender and Job.
I have 6.5 with this formula:
=AVERAGEIFS(F2:F5 F2:F5,B2:B5,B2,A2:A5,A2)
It simply gives the average of 2 and 11, as they are the only 2 male artists in my sample.

If you do not like the idea of additional column, then making a PIVOT table would be a good solution.
Been working on an industrial solution since December. Narrowed it down to daily 4 variables.
Columns of variables A B C D
Day 1 Results 2 3 2 2
Day 2 Results 2 3 2 3
Using the and function, I combine the day to day change into a single number 23222323
I then have a table with all possible outcomes
Lookup Table Of Possible Results In Ascending Order (Expressed as whole numbers)
22122212 Fail
23222323 Good
23233333 Poor
33202322 Excellent
33333322 Undetermined
I can't figure out how to look up the daily result of a built up number using the formula A1&B1&C1&D1&A2&B2&C2&D2 to a table of real numbers in order to return the result "Good" in this example.
Try this:
=VLOOKUP(A1&B1&C1&D1&A2&B2&C2&D2,<lookup_table_range>,2,0)
If your 22122212 (for example) is stored as a number in the lookup table you will need to convert the lookup value to a number as well.
=VLOOKUP(--(A1&B1&C1&D1&A2&B2&C2&D2),<lookup_table_range>,2,0)
