I have 3 columns (B,D,F) that have 15 minute data intervals and I need to calculate the hourly averages for each column but here is the catch, I need to do this from July-1-2011 00:00:00 to Sept-31-2011, 24:00:00 (that's 26,217 data points and 6,554 =average() calculations......
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?
Excel vlookup function returns #VALUE when the lookup value exceeds 256 characters. I need a hash function to transform large strings into a value that does not exceed the 256 character limit.
I am wondering if there is a function in excel to calculate the average of multiple percentages. Currently I rely on the following formula to achieve this result and I am curious if there is a quicker way:
Try this formula. .....
Just today I learned there is a function to calculate the compounded return (FVSCHEDULE). It does part of what I am looking to do by taking away the PRODUCT function and the array, but does not really simplify things. Using FVSCHEDULE my function would look like ....
Situation: I need to calculate a lot of averages of non-connected values. That is, they are separated by several rows (which also contain values). So far, I use the code-sample below (just to illustrate), which is not really elegant. Unfortunately, it seems that this technique comes to its limits when a high number of different non-connected values are combined into one string and get assigned to a formula- range (last line of code), which is where the program stops.
My question is: Is there a nice way to solve this? A way, which is not limited by the amount of data processed? The only way I could think of, would include a UDF, where a sum, sums all values up and then devides by the number of added sums ... but this would be relatively slow, and I have an awful lot of values to be averaged (100 sets * 6 rows * 200 values = 120.000 calculation- steps), as well as STDEV and a Standard Error of Mean (SEM) to calculate. Is there a better alternative?
Const intCells=9 'actually, this is no constant but a variable Const i=4 'actually, this is no constant, but a nested for- loop-value Const intLinesInBetween = 12 ' amount of lines, which separate my values Dim j As Integer 'simple counter, runs through all cells Dim rngUpperRow As Range 'Range of the upper row = normalized time vector Dim rngCurrentRowAvg As Range 'current row into which avg formulas are inserted Dim intCells As Integer ' amount of experiments in range............
On another thread I found a solution to creating a weighted average given a pair of columns of numbers but I have column B consisting of values given as High, Medium and Low and the weighted column C of 1, 2 or 3.
How can I use the formula below to accomplish this, or is this maybe not the right way to created a weighted average?
The names are not static and can be moved, meaning that John can be 1, 2, 3, or 4 (all depending on how the name is chosen). I want to find the average on where John ranks. In this instance, he would be 2 [(1+3+2)/3].
My question is - How can I create a formula that will look for where John appears in the column (B1) and call the previous cell (A1)? This formula needs to be repeated on each column, added and averaged.
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 have a large sheet of daily river flows and precipitation amounts, over 40+ years.
I want to calculate the average flows in each month of each year (ie 11/1968, 12/1968, 1/1969 etc). Dates are in Col A, flows in Col D.
How to average a particular month over all years like so:
{=AVERAGE(IF(MONTH(A2:A15282)=1,D2:D15282))}
But I don't know how to average per month of each year, or how to make a formula that will allow me to quickly calculate the averages of 100s of months.
I am trying to calculate final grades with weighted averages. However for the final grade I need to drop the lowest of the test grade which come after the bold line to the right, making the total relative weight of Tests, the weight of 2 tests. How would I go about calculating that with a SumProduct formula? I do not need to drop grades from B4:K4, however from L4:N4 I need to drop the lowest grade for my final grade, which needs to be rounded to the nearest integer. The relative weight of each assignment is given in Row 1.
I need to do the following and can't figure it out. How do I create a running average that will only calculate the averages in % each month. Example: Opt 1 for Jan, Feb, Mar =1 each= 3 total = 100%; OPt 2 for Jan, Feb, Mar =1,0,1= 2 = 66%; Opt 3 for Jan, Feb, Mar = 0, 0, 1 = 1 total = 33%. My problems is I want monthly running average that shows the yearly percentage up to date but only for the months there is a value 1 or 0. How can this be done because the way I have it now, those % are being divided by 12 and that isn't the correct %
String Multiples for 3 different criteria in same cell -- "if", "or" "abs" --- not sure if any of these are correct
1) Criteria 1 and 2: In cell "E" I am wanting to minus "B from C", if "A" is greater than or equal to and less than "=>1000 or <15000"
2) and the other criteria would be if "A" is greater than or equal to ">=15000" then minus "b from d" -- answer would also be in the same cell "e".
I hope I am saying my needs correctly. Basically, I have 3 different sales criteria with 3 different bonus offers. One offer is for sales less than 10,000, another offer is for the range 10,000 to 14,999 and the last is for the range 15,000 or more. I am actually linking the values from different worksheets, however I have used generically "A, B, C, D and E".
below are the 3 separate formulas that do work on specific individual rows. However, I really need the criteria for all three variables in the same cell. Right now I am just copy/paste the appropriate formula that fits the specific value in each row.
I am looking to calculate variance across a large data set and would like to know if a macro is possible to calculate for a specific unique cell ID. East, Central, or West and calculate variance across that region.
For instance, in my data set if I have something similar to below. How would I calculate variance in the different regions? Is it possible to automate this process? Also could the Analysis ToolPAk be used instead or in conjunction?
I'm trying to do a binomial distribution summation as part of a VBA function, and have been using the Application.WorksheetFunction.BinomDist function, which works fine until the numbers get large - the binomial coefficients used in the calculation end up being larger than can be held in a double floating-point number in VBA, so excel can't handle it. The final result of the calculation is a probability, so it's not a huge number! I was wondering if anyone knows an alternate way of calculating binomial probabilities which avoid any huge number intermediates.
We are trying to find the median of a large set of numbers to calculate the median income in 2010. For an example we have 8,379k people with $2500 average income, 9,783k with $7500 average income and so on. How can I calculate the median average income of such a large amount of entries?
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 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?
