# Rolling Average That Excludes Zeros

Dec 7, 2006
I've got a worksheet that has chronological quarterly data for which I'd like to do a 5-year rolling average. The layout is: Column A = Dates, Column B = Values, and Column C = 5-year Rolling Average. My problem is that I want to exclude zero-values from the averaging calculation. I tried the following:

={AVERAGE(IF(B1,B5,B9,B13,B170,B1,B5,B9,B13,B17))}

However, Excel will not accept this formula (I assume an array must be contiguous? Please let me know if that's correct).

I am working with averages of ACT scores and Class rank percentages. I cannot figure out how to exclude all the zeros and/or DNR (do not rank) values that are in those columns. For example if I have 10 items, and 2 are DNR, the I want to exclude the 2 DNR's in my average. I tried putting it in the Row or Column area and unchecking what I wanted to exclude and then drag it into the data area, but that didn't work either.

I have a spreadsheet which has data in the format of:

Date

Sales

Monday, 8 July 2013

191

Tuesday, 9 July 2013

180

[Code] ....

I calculate the average of the last four weekdays individually with =Average(A1,A8,A14..) in a cell above them to get a four week average.

Each time I add a new weeks worth of data, I manually adjust the formula to remove the first cell, and include the latest cell with new data.

I'm looking to find out if there is a way I can automate adjusting the formula so it always grabs the last four Mondays (for example)? Either in VBA or a formula.

Could you please supply a formula that will calculate a four week rolling average of column B in relation to the dates in column A? I tried using the average and offset functions but can't quite get it to calculate the correct averages.

I'm looking for some help to create a rolling 12 mth average. To explain better I have added a copy of the part of the sheet to help you understand what I am working with.

What I'm looking for is the 12 mth average to show up in cell c26. I have the mths listed in cell A2-A25 and the data I want averaged is in C2-C25

An additional problems is that I only want the 12 mth avg calculated if data in the next mth is greater than zero. Meaning since this month is Mar-09 (which is already collecting data) I dont want to include Mar-09 data yet. I only want to know Mar-08 to Feb-09 average. Once data is returned to Apr-09 then I want the average to show for Apr-08 to Mar-09 and so on. I dont what is better to use vba code or a formula which ever is easier.

Or if someone has a better idea please share.

I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below:

...

C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ...

E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ...

G9 111568 298021 12940 31645 181797 36996 ... ....

...

I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?

Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly

I am trying to create a formula that looks for the last populated cell, counts 12 cells back and returns an average for all of the cells in that range. I know I have done this before with some combination of INDEX and COUNT, but I can't seem to remember how I did it and my experimenting is not proving fruitful.

Attached is a simplified version of the layout I am working with

See Attached.

The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.

At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.

Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?

What I have is a spreadsheet with a whole bunch of sporting data on it. see attachment for an idea of the layout, Stats.jpg

In these data each round a player is given a rating. What I want to do is calculate is the average rating for each player across the last 3 and 5 games they have played. When a player misses a game they get a rating of 0 for the round. I want 0 ratings to be ignored in the running averages. Additionally, games yet to be played have a 0 in the cell and should be ignored. To get overall averages ignoring 0's was simple I used the averageif function, but I couldn't figure out how to use that but only extract the last 3 non 0 values. I currently have data up to round 12, so if a player has played in 12, 11 and 10 then the 3 round average should just be the average of these 3, but if they missed for example round 11 then the 3 round average should return the average of 9, 10 and 12.

The data is set out in the following way.

In column B I have a list of player names from cells B3:B618.

Across row 1 from N1:AM1 are labels "round 1" "round 2" etc.

The ratings for each player in each round are in N-AM and from 3-618. i.e. N3:AM3 contains the weekly rating for player 1, 4 contains player 2 etc.

I would like the 3 round averages to be returned for each player in column L and 5 round averages in column M.

I have the formula for calculating a 13 week rolling average, but I need to be able to set goals in the future and still have the average calculate from current and not from future.

I have my dates set up in row 3 (these dates are all mondays, not every day) and my data in row 4. I need the 13 week rolling average to calculate starting from the prior monday and going back 12 more mondays for the 13 weeks. IE: This monday I'm running reports that the info will be entered into the previous week's monday.

Here is the formula that I'm currently using: =AVERAGE(OFFSET(K4,,COUNT(K4:BV4)-13,,13))

The formula works but will calculate the average for 13 weeks prior based on the last cell with data in it. It's calculating the average of the last 13 weeks of next year.

how to make this work without having to remember my weekly goals every week??

I am trying to create a rolling 30 day average based on a date in a particular cell. I have 62 columns that I am looking at. We can call A1 7/1/14 and the 62nd column 8/31/14 for simplicity sake. I want to grab 30 values in row 2 as these columns are filled in daily so 8/1/14 takes the average of 7/2/14-8/31. On 8/5, I want 7/6-8/4 so on and so forth. The average that I need has to include at least one averageif stating that only nonzero "<>0" figures should be tabulated (just have business day transaction data but need all dates listed to tabulate 30 days). The range of dates will be fixed every month and info copied to tabulate on the first day.

I've got a "Date" Column which has every day of every month, and next to that several columns with different types of data to correspond to a particular date.

To simplify this (because there are TONS of dates), I've made another "Date" column that displays only every 5th day. Now what I'd like to do of course is average the corresponding data over five days.

I don't know how to write a single formula that I can copy down that will do this.

I've attached a sample spreadsheet with only one month's data, the stuff I need a formula / code for is in red

I am using a formula to include all values greater than zero in my average which has worked fine until i tried to extend the parameters, then it gives me the Value? sign. Does anyone know another way to accomplish what i want?

here is what i am using now.

=average(if(BZ28:CM28<>0, BZ28:CM28, " "))

i was trying to make the CM extend to CS, but for some reason it is not working.

Anyway, i figure a different equation might be better than what i

have and solve my problem.

I want to take an average of only non-zero numbers in a range of cells containing a few zeros. I know there is a function to do this, but I haven't been able to find it. With the normal average() function, the denominator is too large as cells with 0 are included.

I current have an Excel doc that I am trying to pull averages from. Every row has data that needs to be averaged but I only need every other cell. And I cannot have zeros in the average because it will skew the data. Also if the average for a row ends up being 0, I want that average to show up as 0 not #DIV/0!. From Column H to EE I need to average each row individually.

I came up with the below formula.

=IF(SUM(H1:H1:J1:J1:L1:L1)=0, "0", AVERAGEIF(H1:H1:J1:J1:L1:L1, ">0")

It works but Its not practical because I have to manually enter all of the cells that it pulls from.

I'm trying to return the average, min and max values of a range that will have errors, be blank or have zeros. I have already found an array formula that works getting rid of the errors but the zeros are now a problem.

{=AVERAGE(IF(NOT(ISERROR(D27:G27)),D27:G27))}

I was thinking that an OR might be needed but for the life of me can't figure out where it belongs. I will also be using this formula with both MIN and MAX in the adjacent cells so it would be great if all I have to do is swap those in for AVERAGE. I'm not keen on how array formulas work, just found an example similar to this on the interwebs, and I'm curious why if the array brackets are removed the value returned is 0 and not an error.

Workbook is proprietary so VB is locked and not an option (not sure if it was but wanted to be clear).

I have a one column of numbers...let's say consisting of six rows

the following numbers 12,0,14,25,0,9

if I average this it comes out to 10

how can I average the same rows but exclude the zeros in the outcome(is there a formula to do that?)

I would like the answer to be 15.....I still need the zero's in the rows however

I am trying to make a excell spread sheet that will calculate my students averages for the year. I need to account for zeros in the coarse and I want this excel sheet to track the current average all year long . So I do not need to include my blanks in the average as I go. Also , how do I formulate my average accum to show this formula - Test scores, four of them count as 80% of the total grade. So each test is worth 20% / Lab 10% of total grade and homework is additional 10%. I downloaded the templete from MSN and have tweaked it to my liking except for the coding above. Please advise. I am a below par on Excel. My attachemtn is below of my templete. One note. the templete gave me the room to include 13 ros of homework - but I will not necessarily use all of them... I can make it one row for home work only ....

Attached is an xls with my formulas and problem. We need a way to factor in zeros in grading student workers. However, we also need a way to omit blank or null cells if the workers did not do a particular project. The formulas currently in the sheet compute zeros for both scenarios, lowering the overall 'grade' for workers who didn't do a project compared with workers who did the project but got a '0'

I have run into a problem with the array formula. After inserting formula with the CTRL+SHFT+Enter it is giving me the same sum to the 3 cells that I had array formulas in but trying to capture different data from what was in the capturing column. Example:

If row F consists of text types: Move-in, Mid Year, and Year End as potential options,and row G is the score for that text type(cells will consist percentages), give me the average of all the cells in row G that are specific to Move-In only, but don't include the blanks in the average.

My existing formula isn't designated to exclude the blanks. how to exclude blanks and how to get it to stop giving me the same result in the three separate cells. My current formula is as such: {=AVERAGE(IF(F2:F73=E76, H2:H73))}

excluding zeros and for excluding hidden rows, but can't seem to find a way to do both at the same time, which is what I need to do.

My company has projects that come and go (and are hidden when they are gone) and at times, those projects return 0s because we do not work on them for a short period... so, when I average a column, I need to exclude both situations.

I would like to average a non-continuous range of cells while also excluding all zeros.

I am averaging hours worked and the hours are found in cells:

B2, D2, F2, H2, J2, L2, N2

Some of these cells contain zeros at this time and I do not what to include the zeros in the average.

I have found formulas that would work but they are all with continuous cell ranges.
