I'm using the following formula to calculate the % relative standard deviation of 5 values:
ROUND((STDEV(C8:C12)/AVERAGE(C8:C12)*100),6)
where C8 through C12 are all 3.48.
I was surprised to see the result of 0.000002, and not 0.000000. This formula seems to be accurate to 6 decimal places when using 5 values that are not all the same. When they are the same, I get this small discrepancy in the 6th decimal place. I attempted to troubleshoot by inspecting C8 through C12. The values were typed in as seen above (3.48) and the cell formatting is set to 2 decimals in each of these cells, so the cells themselves shouldn't be contributing to the issue.
I am using the find method to search column headings, and based on the results copy the column to another worksheet. Everything works fine except if I have a mixed text and numeric string in the cell, for example DT35. In this case the macro doesn't copy this column. I have attached the spreadsheet. CTRL - A will run the macro. The macro calls a form with checkboxes, captioned using the values in the worksheet titled "Set-Up". If a value is found in the column heading the checkbox is set to true, then when the "Copy Selected Columns to Final Sheet" button is selected the columns are copied to the "FinalSheet" worksheet. I tried using xlPart instead of xlWhole, and this works but I need to search for exact strings so xlPart isn't a great work around.
In the attached file I used =MATCH(TRUE,INDEX($B$2:$B$10="",0)) to retrieve the location of the first empty cell.
When using the "Evaluate Formula" tool, it is clear that the position in the array created by the INDEX function is the 6th. Nevertheless, the final outcome is 9, being the last cell in range.
If I create a simple conditional statement in a cell:
=IF(A8="NX-QSNT",B8, "")
I get the expected B8 cell contents when "NX-QSNT" exists in A8, or blank when it doesn't.
If instead of qualifying this full string, I try to Search for the "-QS" string in that cell as the criteria:
=IF(SEARCH("-QS",A8),B8, "")
I get the expected B8 cell contents when "NX-QSNT" exists in A8, but I get "#VALUE!" if it does not find this "-QS" string.
I'm guessing it may be because SEARCH isn't actually returning a TRUE/FALSE response, but rather, a numeric one based on the position of "-QS". I tried using a numeric approach also, but this didn't help:
I have a worksheet containing data in columns. For each column, I would like to calculate the standard deviation of the mid-95% of the values i.e. 2.5th percentile to 97.5th percentile (to reduce the effect of "outliers").
So first of all I calculate the values of the 2.5th and 97.5th percentiles:
I have a set of values. #N/A413636363632. The #n/a is there on purpose for charting reasons. How do I calculate the stdev of that range? i.e. ignoring the error?
If I have 50 data points sorted in order (oldest --> newest), how do I do a stdev function that will only pull the 24 most recent points?
Essentially, I have 14 columns with 50 data points each. At the end of the list (or maybe beginning - under the column header) I want to do a stdev calculation referring to the most recent 24 points and a second for the most recent 36 points.
I'd like to calculate the standard deviation and mean of a whole load of data. Unfortunately it has some errors, FALSE values, blank cells and zeroes I'd like to exclude. Calculating the average is no problem as the AVERAGEIF function works fine, but there is no equivalent for STDEV. The (array) formula
STDEV(IFERROR(E29:E32,FALSE))
ignores the cells with errors and calculates the SD, and the (array) formula
STDEV(IF(E29:E32>0,E29:E32,FALSE))
ignores the cells with a value of 0 in them and calculates SD.
The problem is the blank cells in the range that I am calculating (M2:M25). Everything is alright if there were no blank cells in M2:M25. If there were any blank cells, however, the STDEV was wrong (the countifs part was correct). It treated the blank cells as zero.
I need to calculate a Stdev and Average based on a specific range. However, my range is not constant in the time. For instance, today I may need to calculate these functions based on 30 numbers, but tomorrow on 25 or 15 or 50...
Is there a way to automate this process by changing the number of data points to include in the range in one single cell and avoid manually adjusting the range in accordance with needed data points?
In other words, I would like to change the value, let's say in Cell A1 from 30 to 50 and then Excel would re-calculate the StDev and Average based on 50 data points and not 30. Is that possible?
In the attached worksheet, we track thickness of a variety of products and record them based upon lot number. I am trying to perform statistical analysis of those products and plot the averages.
Our products are in roll form. We cut to specific widths and lengths from these "master" rolls. We take 3 measurements across the width and several times throughout the roll length. We can have multiple rolls making up 1 lot and due to demand switch between products and try to use FIFO but that doesn't always work. I have keying in historical data and realized my standard deviation is way off but I don't know why.
Have an optimization question for you. I'm starting to try to optimize my macros and I've heard/read it's best to not activate or select anything. - I assumed that meant it would be more efficient to run code without it.
I have a loop I run through about 600 times that takes .75 to .85 seconds to run through with the following piece:
I've got a user form with 12 textbox, one for each month a total textbox number 13 and a 14th text box (TB28) to enter $'s in.
AfterUpdate in each textbox 1-12 posts its value to a worksheet all values are summed in a =sum range which in turn populates textbox 13. When TB13.text = 100.00 it sucessfully calls a number of routines but what I can't get it to do is set focus on TB28.
Private Sub TextBox13_Change() If TextBox13.Text = "100.00" Then With FormPhasedAmt.TextBox28 .SelStart = 0 .SelLength = Len(TextBox28.Text) .SetFocus End With End If End Sub
It returns a Run time error Unexpected call to method or property access highlighting .SetFocus. The rest of the code works OK. Is it because other textbox on the same user form have text highlighted because of the tab order?
I have a list of numbers and i want to calculate avg and stdev but i do not want "zeros" or "blanks" to enter into the calculations. I have a formula for avg but i need one for stdev.

I have a macro, operating in my excel document. It works and does it's function. The only problem is every time this macro is running I get the run time error 1004, Method 'SaveAs' of object '_Workbook' failed. After clicking End in the error window it opens up a newly created sheet that I need. I don't need to save the file in the desktop, I need it just to open up like it does right now.
It will perform the sub-totalling for the column that has the current active cell
When I select Column I
It does..... -for each blue cell it finds it provides a total of all the white cells bellow it -for each yellow cell it find it provides a total of all the blue cells bellow it until it reaches a yellow cell
It works backwards, so not exactly as I've just described, but that isn't the problem
Problem is - UK Excel 2010 - results are as expected US Excel 2010 - returns zero values for totals
We've possibly narrowed the problem down to when it looks at cell properties, more specifically -- If Cells(rowX, 1).Interior.ColorIndex = 20 Then
How to get results in blue and yellow cells when you select a cell in column K then execute the CreateTotals macro.
I have a little spreadsheet aplication which ran perfectly in Office 97, but since the move to Windows/Office XP, I get the message:
Solver: An unexpected internal error occurred, or available memory was exhausted.
I'm running a P4 2.26GHz with 512MB RAM.
My code is as follows:

When I close one excel document, I get prompted for a password.. And it won't close (I don't know the password) The only way I can get it away is by terminating it in task manager. I have read alot of threads in here, where the solutions should be to uninstall Google Desktop..
This is a floowup to the issue that was originally posted as "Returning MAX/MIN values from multiple rows in a named range ". I marked that post as solved since I have worked through part of the issue and since have a different one.
When I drag my VLOOKUP formula down a column in Excel 2010, the return value copies the formula result from the original VLOOKUP formula result. For example, if the first VLOOKUP returns a value of 0.5, I expect to see 0.5 or 1 in the cell below that one. However, I get 0.5 which is not the expected result for the cell below.
When, I click the fx on the cells below, the expected return values appear in the formula result. After I click OK, the expected formula results updates and now appears in the cell.
I'm not sure what is causing this issue. My computer was updated recently from an old machine to a new one. I have never experienced this issue before.
I have excel result sheet which contains students information. i.e. name, subjects and their corresponding marks, grade, percentage etc. So from that sheet I want to print result cards for each students separately from the data (result sheet).
I have 4 categories A, B, C & D. These are in desending importance, means A is most important and D is least important. Now there could be many A, B, C & Ds listed in a column. The challange is if coulmn contains A anywhere then the result should be A. If A is absent, then search for B, if present anywhere then display the result as B. It doesn't matter how many times A or any character is listed in column. I am attaching a sheet for better explanation.
I created a simple auto numbering function whereby Cell A7 contained =Row()-6, and Cell A8 contained =(A7+1). I then shift, and pasted the contents of cell A8 until cell A600. My aim is to simply copy the increments of 1 - 600 into another column. However when i copy and paste i'm also copying the initial underlying formula ie: =( A?+1), Is there a way to copy the results, not the formula?
I have a macro that imputs data from an external database and puts it into a temporary worksheet. This data has 3 columns (ID, Date, Amount). I am then making another sheet which has X number of tables (one for each ID), with the years being the column headings, and months being the row headings. ie.
| ID X | +------+------+------+---> | | 1999 | 2000 | 2001 | +------+------+------+------+---> | Jan | $100 | $250 | $300 | +------+------+------+------+---> | Feb | $200 | $300 | $200 | +------+------+------+------+---> | Mar | $300 | $250 | $100 | +------+------+------+------+---> | Sum | $600 | $800 | $600 | | +------+------+------+--->
| ID Y | +------+------+------+---> | | 1999 | 2000 | 2001 | +------+------+------+------+---> | Jan | $100 | $250 | $300 | +------+------+------+------+---> | Feb | $200 | $300 | $200 | +------+------+------+------+---> | Mar | $300 | $250 | $100 | +------+------+------+------+---> | Sum | $600 | $800 | $600 | | +------+------+------+--->
Currently I have a few hidden fields for the DSUM Criteria. I start making the tables. And then filling in table based off of the month and year. Doing so I need 3 criteria: >= First Day of the Month <= Last Day of the Month = ID #
The problem is it takes Excel too long to fill in the 3 criteria fields, calculate the result, copy the result, and place it into the correct place on the table. Is there another way to get this data into the correct tables faster? Instead of using DSUM?
I've got results in row 3 - 16 386 and sometimes these results are exactly the same in some rows. What I now would need is row AB to display only one of each result and row AH to display how many percentages of the time this particular result appears.
I have a cell in which numbers are displayed. The next cell is a calculation to display percentage. Lets say Cell A1 = 12,45. Cell B = 12%. What I would like is for cell C1 to sometimes display the "12,45" and other times the "12%". I imagine I have to get excel to see the % sign as text, but I do not know how.
I have a formula that looks up a cell reference, if has a custom format to read "Days Left". If the result is zero or less i'd like it to show "Completed"
