# Moving Average Ecluding Blank Cells

Aug 15, 2007
I have a column of data that contains various blank cells where no data was measured. In the adjacent column I want to take the moving average of the last 4 data points including the most recent entry. My problem is i do not know how to handle blank cells where there was no data. I need it to average the last four in the column where data acutally exists. I am ok with using helper cells if needed and I am not worried about the first four results at this time.

Example data

A..................B

15

50

25

20................55

Blank............55

30................31.25

35................27.5

blank............27.5

blank............27.5

15................25

10................22.5

15................18.75

40................20

blank.............20

I am looking to remove all blanks from a table I have and move all the data left. Right now the data is by date, and some dates are blank for some players (it is a basketball sheet) and filled for others, but I want to see it by game. So I have what is in the first table below, and I want it to look like what is in the second.

2-21-2014

I am having a dilemma on getting the average for the first 3 non blank cells. This is how my data looks like :

excel average.jpg

I don't know any formula that will disregard the non blank cell and will get the average of the firs 3 non blank cells from the right.

I have a problem and I found a good explanation of something similar here:

[URL]

In the original posting the following formula solves the problem (attached) TestData.xlsx

B1: =AVERAGE(INDEX(B3:B100,MATCH(TRUE,B3:B100<>0,0)):INDEX(B3:B100,MATCH(TRUE,B3:B100<>0,0)+4))

What I would like to return is the average of the 1st 5 values, but what if a number of cells after the first value were also blank

I am doing an average of a column of cells. How do I tell excel to ignore the blank cells in the column and not calculate them in the average?

I have a scenario where I have a rolling list of sales figures which get added to each week that passes.

I need a formula that will calculate the last 5 weeks of sales and generate an average - which I think I have an idea how to do.

The sticking point is that so as not to skew the averages, when there has been an exceptionally busy or quiet day for a reason we know about I exclude the sales from that week.

This then interferes with the averages as it either takes it as a zero and lowers it or seems to stop formulas from working.

So to summarise:

Average of last 5 weeks sales

Excluding any blanks

Dynamic enough to always pick up the last 5 values in the list (i.e. the last 5 weeks)

I have an array formula that calculates the average of numbers between two dates:

{=AVERAGE(IF('Date Range'!$B:$B>$H$4,IF('Date Range'!$B:$B<=$B$3,'Numbers to Sum'!$C:$C)))*100}

The start date is the day after the date in H4 and the end date is in cell B3. The dates are in column B and the numbers to sum associated with these dates are in column C.

Some of the cells in column C are blank and my formula is taking these blanks into account in calculating the average, while I would prefer not to count them in the calculation.

Can someone please suggest how I could amend the formula above to accommodate this?

I've got a spreadsheet that I do every month with columns of numbers that I average. This sheet has to match about 10 others similar. The columns are divided by Weekdays, Saturdays, Sundays. But some months there are no entries for certain cells on Saturday or Sunday.

I thought that if I just used the Average function, it would dismiss and not count the blank cells. Alas, apparently not. I've highlighted in yellow the one column that I'm really having trouble with.

I am trying to get a rolling 8wk avg of a large group of data. I am trying to take the avg of 8 vlookups:

=AVERAGE(VLOOKUP($A$9,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-7,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-14,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-21,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-28,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-35,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-42,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE),VLOOKUP($A$9-49,'Raw Data'!$A:$DV,MATCH(B8,'Raw Data'!$2:$2,0), FALSE))

However, in some cases, the cell to be looked-up may be blank. Using the formula above, the result of these vlookups is "0". I want to take the average of these vlookups excluding the blanks from the 'Raw Data' sheet.

I have a sequence of 40 columns of data, representing 10 weeks worth of events with 4 values per week

I need to average the first pair for each week, ignoring zeros and blanks, and also separately the 2nd pair of cells, across the whole 40 columns

I am trying to come up with a neater solution which takes into account the zeros, at the moment I have the following which does not, for row 34

=IF($AR34>0,ROUND(AVERAGE(D34:E34,H34:I34,L34:M34,P34:Q34,T34:U34,

X34:Y34,AB34:AC34,AF34:AG34,AJ34:AK34,AN34:AO34)*2,2),0)

I could use SUM, COUNT COUNTIF etc but its gonna get messy

Is it possible to show "0" zero in the total average column without inputing zeros in the blank cells in row B3:E3 & B4:E4? There are months we receive no boat & RV orders, so those months wll be zero most of the time. Instead of having #DIV/0! it show 0, without having to input zero in cells to compute the average.

Here is the formula I am using however it interprets the blank cells as 0% and includes it in the average. To make it more difficult there will be some 0%'s.

I'm looking for a function that will display the average of a row of cells, while at the same time not displaying any error messages. It's easy to average cells without blank values, but to combine that with no errors is difficult for me. I saw many ways to do the average, one of which is:

= SUM(A1:E1)/COUNTIF(A1:E1,">0")

That function doesn't work for a row of blank cells (i.e., hidden rows), though. The result is an error message.

I also read about a way to ignore an error in a computation:

=IF(ISERROR(F1),"",F1)

The problem is when I combine those functions I get a blank cell no matter which function I put first, and without regards to cell values or not. The reason I want this to be error-free is that I have to average the "average column" at the bottom of the table, too (i.e., F100).

this User Defined Function (UDF) would operate on any specified data (ignoring blanks) over a range. Inputs to the UDF are range and period.

In the table below I'm trying to work how trend is being produced but I can't figure it out.

I have found how to find the moving average =AVERAGE(C2:C5)

I've tried a few methods using the trend function but I really don't understand what I'm doing. how its being calculated by looking at the table?

I have a set of data in column A consisting of over 1200 numeric values. The problem is that there are some blank cells in this column:

Colums A data:120, blank, 135, blank, etc

I need to calaculate the average for the first 25 data and then claculate the average for the next 25 data set dropping the first 5 and adding new consecutive 5 data ignoring all the bank cells!, so if the first statemnet is : averagre (a1:a24), the second statmnet should read (a6:a:29) not counting the blank cells. I don't know what array formula can be used to do this job for me.

I am trying to do a moving average and running into an issue with the count part of the formula.

Column C (C2 to C54) has the numbers I need to average.

Average is based on last 5 weeks.

My issue is that C23 is blank as we had no data for that week.

Currently the formula is counting 25 entries between C2:C27, there should be 26.

My average should be 31 but I am getting 33.

This is the formula I am using :

=AVERAGE(OFFSET(C2,COUNT($C$2:$C$54)-5,0,5,1))

I have tried using different Counta and ISnumber still not working

I would rather use a formulas then VB code.

I have done quite a bit of looking on Google and looked over the posts in this forum, however, I can't find an example Excel worksheet for a linear weighted moving average.

The data set I am applying this to has 180 data points and the linear weights should extend back over the last 30 points.

I am using the built in moving average function to calculate the moving average of a set of numbers. There are a few things that i would like to do.

First i would like to have the last result displayed in a single cell. Then next to that cell i would like to have a cell that would specify the period of the moving average. I would like to be able to change the period in that cell and have that change it in the actual function. And finally i would like to have the moving average in a chart that would also change its period once that is changed in the respective cell. I realize that this might need some VB coding which i am currently learning.

I would like to calculate the moving average for the first ten rows in a column where each new entry is added to the cell above the last entry.

For example

A5, 2

A6, 3

A7, 4

A8, 5

A9, 6

A10, 7

A11, 8

A12, 9

A13, 10

A14, 11

A15, 12

Therefore in the current list the average is AVERAGE(A5:A14)=6.5.

The next entry added to the list will be in cell A4 making the list look like this

A4, 1

A5, 2

A6, 3

A7, 4

A8, 5

A9, 6

A10, 7

A11, 8

A12, 9

A13, 10

A14, 11

A15, 12

The average of the first 10 cells is now AVERAGE(A4.A13) = 5.5

I would like to enter one formula in say cell A1 that will calculate the moving average in the first ten cells each time a new entry is added. Naturally as needed, new rows are added below cell A1. I hope my problem is clear.

as I have been unable to solve it myself. I have tried using offset but have been unable to resolve the issue.

The following code works fine if the data is sorted from oldest to newest. I need for it to work when the data is sorted from newest to oldest. For this to work, I would need a change that works something like this: "total1 = total1 + close_(a, 1) * a" would be "total1 = total1 + close_(a, 1) * b" with "b" incremented in the opposite direction of "a". I code very infrequently & have tried a lot of different things, searched the Internet, etc. all to no avail.

For instance, with "close" data in column "I", the data sorted as follows works with the formula

"=WMA(OFFSET(I2,0,0,9,1) )" to correctly return "791.50", but the opposite sort returns the wrong number.

The correct calculation is: (807.19*9+798.38*8+793.81*7+793.06*6+776.28*5+769.48*4+773.2*3+789.01*2+793.87*1)/(9+8+7+6+5+4+3+2+1).

11/12/2012793.87

11/13/2012789.01

11/14/2012773.2

11/15/2012769.48

11/16/2012776.28

11/19/2012793.06

11/20/2012793.81

11/21/2012798.38

11/23/2012807.18

Code:

Public Function WMA(close_)

total1 = 0

n = WorksheetFunction.Count(close_)

divisor = (n * (n + 1)) / 2

how do I perform calculations on the last x non-blank instances in a data range?

for example, let's say I have a spreadsheet of 5 baseball players' batting averages (rows are team game number played, columns are at bats and hits for each player). I want to see how each player has performed in their last 10 games played, but some players have not played in every game. If I just use the sum function for the last 10 cells, I won't get the correct information for any player that has missed one or more of the last 10 games.

Currently i have a spreadsheet with realtime data feeds from Bloomberg (or reuters). What i would like to do is:

a. Fill a vector/column of data values every minute until we have 30 observations i.e. from 9.00am till 9.30pm

b. This will then allow me to calculate a moving average of the last 30 (1 minute) observations.

c. At 9.31am, the 9.00am value drops out of the column and is replaced by the observation at 9.31am. This results in a constantly updating column of the last 30 minute observations and will allow me to have a realtime moving average.

I have a worksheet that has all weekday dates in column 1 and values in column 2. I want to create a 30-day moving average based on the last (non-zero) value in the column 2.

Since every month has a different amount of days, I want it to search the date that has the last value (since I don't get a chance to update it daily) and go back thirsty days from that date and give an average of all the column 2 values skipping and values that are null or zero.

E11 through E24 contains numbers and a few errors (#N/A) that need to persist (the errors need to show).

E10 needs to show the average of the numbers that are in E11 through E24, and just ignore the errors.

I have many columns like that - where the errors need to show and I need to show an average of the number/values that do appear, ignoring the errors.

I have a pivot that includes customer data and I need to create an average for each row based on the first populated column for each customer. After one month of units appears for the customer, I need to calculate the average going forward, and if there are blanks after that they should be treated as 0 in the average. Below is an example of my description of the pivot.

Jan Feb Mar Apr

Customer #1 1 1 3

Customer #2 1 3

Customer #3 2 2

So, the average for customer #1 would be calculated from Column B to Column E, and factor column D as a 0 in that calculation. Customer 2's average would start in Column C and go to Column E, and factor column E as a 0 in that calculation. Customer 3's average would start in column D to column E.
