Averages With #N/A In Row/column
Jan 13, 2009
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.

I have multiple sheets each containing multiple columns of numbers, and sometimes when the numbers are not present there is a text error string such as "#N/A N.A.", or "#N/A N Ap". An example of the data is as follows:
4.06
1.28
3.411
#N/A N.A.
2.627
1.157
4.9
4.9
2.963
I would like to put geometric averages of each column from each tab in a summary tab.
* I tried using =GEOMEAN(...), but it can not handle the quantity of data that I have nor can it take non-numeric fields.
* Also Tried something like this =EXP(AVERAGE(IF(ISNUMBER(C:C),LN(C:C)))) as an array, but unless cells are specified explicitly, ie c10:c300, I get an answer of 1. I can not specify the cells because I have a variable height of each column.

I have a first column, which contains random integers typically with gaps of between 10 to 50 blank cells. The data may have up to 5,000 rows in total.
In the next column along I would like a calculation which averages the integer in the first column out across all rows until another integer is reached in the first column.
E.g. In the first column, the first number is 60, then 9 blank cells till the next entry. In the second column the first 10 cells each contain the number 6 ( = 60/10).

I am working on a spreadsheet which has a column which shows square footages (Column AE) and I also have a column which shows costs (Column Y).
What I would like to do is to bracket these footages in to 6 bands (0 - 5000, 5000 - 10000, 10000 - 15000, 15000 - 20000, 20000 - 25000, 25000+) and then average the costs within a particular band.

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.

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 using the formula =AVERAGE('Year 13'!BV:BV) to work out the average value in column BV.
However, I would like the value to change if I filter one of the other columns, is there any way to do this?

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.

In the following cells I have an average:
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.

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?

The first one, I do i remove #DIV/0! from cell O7 in the worksheet "My overview"?
The second one, I need to get averages of the QA score for the 3 months from January to March in the worksheet "My Overview" Cell E14 for the corresponding person on each sheet. I understand that there need to be values in place to get an average but is there a way to overcome this?

I created an Excel tool into which really thousands of records are based on weighted averages calculations. And discovered Excel struggling in term of permormance.
The issue is: the user needs to uploads a couple of times in a day new data for further analysis, and the only way to make the Excel spreadsheat humanely usable (performance) was to calculate everything upfront.
To optimize the tool performance, I had to:
- First I made all weighted average calculations upfront when data is uploaded the first time. Leaving formulas in the tool was not viable, since this tool run live analysis, every click would have been a pain of 30 sec at best to re-calculate new conditions,
- Second optimization was to not leave formulas into columns > as soon as a calculation is done, the macro copy/paste values
The formula I chose is sumproduct based weighted averages..
Here is my question:
1. Does it exits specific formulas in Excel to handle nicely large amount of weighted averages to calculate ?
2. Should I consider to use an external application (an Access table, SQL or whatever) to perform those weighted average calculations quickly/quicker.

I have a spreadsheet that we are using as a Skills Matrix for the team. The area that the team member deals with is listed in Row 3. The scores for each person are recorded in Columns D to M. The process steps being scored against are in Rows 8 to 38, and are seperated by the area of responsibility.
I am trying to work out the average scores of each person depending on their area of responsibility. I can work out the totals easily enough using:
=IF(ISNUMBER(FIND("CM",D3)),SUM(D11,D12,D13,D14,D18,D19,D20,D23,D24,D25,D26,D27,D28,D29,D30),0)
+IF(ISNUMBER(FIND("V",D3)),SUM(D33,D34,D35,D38),0)
But if I use the same for the average scores is works fine until a person covers two duties:
=IF(ISNUMBER(FIND("CM",D3)),AVERAGE(D8:D10,D12:D17,D19:D22,D24:D30),0)
+IF(ISNUMBER(FIND("V",D3)),AVERAGE(D31:D32,D34:D37),0)
This is becuase it adds the 2 averages instead of working out the total average score. Is there an easy way around this?
i.e. For team members who have CM in Row 3 I need an average of certain cells, for team members who have V in Row 3 I need a different average and for those team members with both CM and V I need an overall average.

I would like to write a formula to average cells F27 - F11007 in a spreadsheet for every 96 values. That is, I want the average of F27:F122, F123:F218, F219:F314 and so on up to F10912:F11007. Ideally I would be able to pull down the fill handle and perpetuate the formula since this is a lot of data.
I've been trying to use INDIRECT and OFFSET formulas but I get a #REF! or #VALUE error.

I need a formula that determines the average of numbers based on specific cells.
For instance:
COLUMN A COLUMN B
John Doe 1.48
Jane X 2.89
John Doe 1.89
Jane X 5.98
Michelle Doe 5
Claire Doe 3
Jane X 0
What formula can I use to give me the average of "Jane X" not taking into consideration the one with the 0 Value?

I was able to record a macro that did essentially everything I wanted it to, with the important exception of getting the right selection for the average=() calculation.
My worksheets are set up with multiple variable columns, and multiple data collection stations as rows. The rows are sorted by date, with a blank row dividing the data by month. There may be 50 rows in January, then a blank row, then 4 rows in February, then a blank, then 15 rows in March, etc. I can easily average the monthly values in, say, column N by typing "average(" in the cell where I want the average to be calculated, then selecting the top cell for the month of interest in column N, holding the shift key down, pressing end, pressing the down arrow, and then typing ")".
The macro recorder, however, doesn't seem able to handle this method of selecting the cells to put inside the formula parentheses. If I try to run the created macro on other months, it will average the same number of cells targetted by the initial example (i.e. the month I was working with when recording the macro).
Is there any way to code this operation so it will vary the number of cells averaged, based on the number of data rows present in each monthly group? My research into coding averages is turning up only examples that deal with whole columns or fixed cell ranges.
Since I have a pretty big stack of worksheets to work though, it would be very nice to automate the process, but I'm still fumbling here. Not getting anywhere.

I have a column of 96 numbers (observations every 15 minutes for a 24 hour period), and I want to take the average of these numbers in groups of four (the hourly average). My data starts in cell A2 and goes to cell A97. My first batch of averages are labeled as follows:
Range("A2").Select
startCell = ActiveCell.AddressLocal
ActiveCell.offset(3,0).select
stopCell = ActiveCell.AddressLocal
Now, clumsy programming aside, I just want to say something like this
averageCell = AVERAGE(startCell:stopCell)

The data was taken in 15 min intervals and is organized by date. I have one column with the date and time and another column with the data. I need to find the average for each day. I have almost a years worth of data. Is there any formula I can enter to find the values in a given day and return the average of the values (without having to select the data for each day)? I want to be able to copy the formula down a column with the value per day.

I'm trying to do something that I thought would be very simple for excel to do. All I want to do is show the average score of the data selected by the selectors in the chart. For instance, in the attached file, I have the following selection (AMER, North America, Canada & USA, Purple) and from this data selection I have 4 columns of data. I would like the chart to show somewhere on the chart the average of the total revenue (both columns) and the average of the GOP. Is there not a way of showing on the chart any data metrics?

DATA: D1:D11 contains either blank cells or a dollar figure from a payroll check.
E1:E11 contains either blank cells or the date of the check.
Current Situation: Using the following formula I obtain a weighted average of the pay checks, not including the largest. =(SUM(D1:D11)-MAX(D1:D11))/(COUNT(D1:D11)-1)
Problem:
I desire to calculate the weighted average based on the checks issued only prior to a certain date. I have used SUMIF() in other parts of the workbook successfully but needing to withold the largest value has presented me with a problem I can not find a solution to. =SUMIF((E1:E11,">="&TargetDate,D1:D11)-MAXIF(E1:E11,">="&TargetDate,D1:D11))/COUNTIF(E1:E11,">="&TargetDate,D1:D11)
