I am working on a spread sheet and am trying to use rolling averages of the last 3 months. I am using worksheets for each month with a final worksheet containing the 3 mo. rolling average. I tried using a formula with OFFSET and it worked fine if all the data was in 1 worksheet, but did not work for multiple worksheets averaging to another worksheet in the same workbook.
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 have a column of data (Column A) and I'd like to build first the Average of the first 20 data points (like in an Excel spreadsheet, cell B21 will contain the average(A2:A21), cell B22 will contain average(A3:A22), and so on... rolling).
I looked up on the internet, but I simply don't know how to start with, I mean, how to name the new array and make it rolling.
Then I will need to calculate STDEV for the same interval, and then Zscore ((Value - Average)/STDEV), but I guess it comes automatic once you made the first part.
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.
I need a formula to give me a ROLLING SUM of the last 12 entries in a column, to give a rolling year sum.
Each month a new number would be added to the column at the end just before the rolling sum calculation.
The formula then would sum the new entry plus the preceding 11 entries. E.g. Cell values as follows: A1=10, A2=6, A3=3, A4=9, A5=4, A6=5, A7=13, A8=2, A9=7, A10=1, A11=14, A12=5
Say the sum is in cell A13, the sum=79.
A row is inserted above A13 and 7 is entered.
Now the sum calculation is in cell A14 and the calculation is from A2:A13 which equals 76.
I am trying to work out the average volume of our daily downloads. I have used Vlookup to automate this. When there is no data it returns #N/A which is no problem. The problem arises when i try to work out the average for the month or peaks (MAX sum).
I have tried several variations of sumif/if/isna etc etc and am not having much luck. Below is an example of what i am trying to average out: #N/A620#N/A
That is 4 different days download data - I want it to ignore the 0's and #N/A and return the average for the days we actually had a download.
If I have a varying number of figures(say between 4 and 10) which I want the average of the first half of the set and an average of the second half, is there a function which I can use to calculate this? ie if there is 8 numbers in total then I need the average of the first four and last four... but if there is ten figures total then I need the average of the first five and last five.
I am inputing each day the total amount of sales. I am manually doing the averages for past 12 weeks on Monday sheet. I would like when I enter the amount for that week that the cells B84, C84, E84, F84 are automatically updated for the past 12 weeks. I have tried a few different approaches but I keep getting #ref or circular reference
We are trying to get an Average between 2 columns that have the same conditions. We have been using an array formula succesfully on data that is on 1 column and I have trying to incorporate an Offset into the formula with no luck. Here is our latetest attempt, WITHOUT THE OFFSET. The data is in Column P and Column N
=AVERAGE(IF((('Mill Process Data'!N3:N6650,'Mill Process Data'!P3:P6650>.01)*('Mill Process Data'!N3:N6650,'Mill Process Data'!P3:P6650<.3))*(ISNUMBER('Mill Process Data'!N3:N6650,'Mill Process Data'!P3:P6650)),Mill Process Data'!N3:N6650,'Mill Process Data'!P3:P6650)))
I want a cell that takes each row in column B and subtracts column A from it... (10-5 for row 1). I want it to do that for all rows and then average that number. This would be easy if I were not using a pivot table with a lot of data.
For example: Column A Column B 5 10 2 9 6 8 1 4 6 7 1 1 6 2 6 8
I havea list of values that I need to work averages out for. Unfortunately, sometimes the values will be a zero and these should be ignored.
I can work out the averages easily enough using the average function, but can't quite figure out a way of ignoring the zeros. Sample data would be :- week 1 - 3.42 week 2 - 0 (zero)
Using the standard average function, I get an average of 1.71 when I actually want it to have an average of 3.42.
I would prefer a function for this but would settle for a macro even though it would increase the program run-time.
B6,J6,R6,Z6, and AH6 and a total average on cell AP6
How would I go about making a formula for that. The reason why I ask is because all the info I have seen refers to the cells with the averages need to be in sequence or range and nothing about the cells being seperated. I also tried using the countif method, but same prob, the cells need to be within a horizontal or vertical range
I need to calculate average for last 12 valid entries in a column. I say valid because if there are blanks or zeros in the cell they need to be discounted.
The solution needs to work on percentages as well.
To explain further Col A Col B Jan 2007 1 Feb 2007 5 Mar 2007 5 Apr 2007 0 May 2007 Jun 2007 20 Jul 2007 0 Aug 2007 Sep 2007 10 Oct 2007 0 Nov 2007 10 Dec 2007 18 Jan 2008 8 Feb 2008 6 Mar 2008 0 Apr 2008 May 2008 10 Jun 2008 1
The requirement would be to calculate average from Jun 2008 backwards for 12 months where there aren't zero or blank entries.
Column 1 contains the number of times an ad has shown Column 2 contains the average position of the ad from column 1
Like so,
Ad Impressions.........................Avg Position Google: 14,220,023..........................3.2 Yahoo: 346,656...............................1.2 MSN: 123,234..................................8.9
Total: 14,689,913............................???
Doing the following,
= Average(B2,B3,B4)
This is not the real average as this is directly influenced by the number of ad impressions...
How can i make a real calculation to give me the true total average position of my ads?
Have a five column worksheet with the column headings run column A1 - E1 and there are currently 112 players filling out the data with many more to come
I have data that is linked and is updated automatically. I am trying to use named ranges for the rolling data for each area and my date range is 5 cells using the Today()-5,4,3,2,1. The dates are rolling fine, but I cannot get the data to update, it stays the same from day to day.
look at this and see what my error is? cookies and kudos(no password on the unprotect)
Alas I need to put more dynamics and fill this data set from other sheets, so I'm putting formula into column A, and this force chart react and insert another category.
In other words I want to have this fill only if data present on different tab(worksheet).
That what I have now:
[Code] ........
COUNTA Counts the number of cells that are not empty and the values within the list of arguments. Use COUNTA to count the number of cells that contain data in a range or array.
I have an excel sheet setup with several tabs which are organized by work days in a week. (i.e. aug 18, aug 19, aug 20, aug 21, aug22, aug 25, aug 26, aug 27, aug 28, aug 29) Sample file has been included.
I would like to do a rolling total of 1 particular cell (the same location on all the sheets, i.e. cell a2 on all sheets) for the past 4 weeks, and it automatically adjusts itself based on today's date (i.e. today is august 27, it will total everything from jul 30, 31, aug 1, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 18, 19, 20, 21, 22, 25, 26.).
Is it possible to do this?
I am not familiar with VBA or Macros, so solutions using either of these will require some detailed explanation for me to understand how to apply them.
One of our govt. agencies requires that I compute the 24-month rolling averages of the daily average input to a manufacturing process. In this instance, the agency is demanding the rolling average since 2003, so there are a fair number of data points involved. The process control computer can provide me the daily data (attached file contains 30 months of data), but cannot compute the 24-month rolling average.
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 need to create a Sum of numbers month to date Rolling. Meaning... if I have a expected number for the month, I need to be able to sum the processed numbers for each day up to the current day excluding any day after the current day.
So the formula would need to sumif the total month numbers UP TO the current day and compare that against the processed UP TO the current day. Month Expected Processed April 1 500 450 April 2 500 450 April 3 400 425 April 4 400 450 April 5 400 April 6 450
What it is, I have a rolling report for the whole year, each with a score for the week.
However, it needs to show the whole year, but I need a seperate box with a summary of only the last 4 weeks on a rolling basis, ideally this would automatically update depending on the week.
See attached for example of what I am trying to achieve. I need a macro which will allow me within excel to roll down within column A a block of the same number for 25 rows, insert a blank row, and then add one to the starting number roll it down 25 rows insert a blank row and so on. I would like to start with the number 031400 and continue until 064300 the leading and trailing zeros are key so I have made column A text field.
My employer uses a scoring system to give a value to an individual’s sick record in the current rolling year.
Each person, has recorded, the number of sickness occasions and the total number of days in this rolling year period, these details go onto the final sheet where a score is calculated.
At present to get an accurate period, I have needed manually to deduct days to produce the correct time frame, ie 27/3/06 to 28/3/07 or when the sikness carrys on into the folling month.
I have tried without success to modify the rolling year formula, which as it is, will include the whole of March 06.
