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.
View 2 RepliesI 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 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.

View 10 Replies View RelatedWe 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?

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'm trying to Calculte the Averages of just the Teachers Salaries in my spreadsheet. If possible i would like to put the average at the end of each

Is there code that would allow me to do so.
I attached a sample file to view.
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.

View 2 Replies View RelatedI need a formula that determines the average of numbers based on specific cells.

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 have a spreadsheet with one "master" sheet and multiple "level" sheets. The workbook is an employee rating system and employees have different pay grades. The individual sheets represent each paygrade while the master sheet averages the total of each criteria for all the paygrades. Look at the image below:
http://www.excelforum.com//attachmen...1&d=1165960332
What you see above is a cutout from one of the "level" sheets to give you an idea of how employees are added to the sheets.
Sheets I have: Master/E1/E2/E3/E4/E5/E6/
The first catch is that the sheets will not have an equal number of "rated employees", so I would need to tell the program how to find the number of employees being rated (and how to reference the columns to find the total scores in). In the example you see name1 and name2... this represents 2 employees. To add another employee they duplicate the 3 rows and create another employee (i.e. name3). Second is that it has to disregard total scores that are "zeroes", meaning it does not average the total scores with a zero.
The master sheet is just a duplicate of the "level sheets" but with 1 set of 3 row columns to average each criteria from the 6 "level" sheets. I appreciate your guys' help in advance. Thanks!

IS there syntax I could use that would calculate the average every 4-cells so I could get the hourly average without having to type =average(XX:XX) 6,554 times?
