I'm working with a relatively small data set, so in order to better identify outliers I'm looking to calculate the modified z-score. However, in order to do that, I must first calculate the median absolute deviation (MAD). how to do this AND show an example of how to calculate it in Excel?

Using excel functions, how can I calculate the mean, median, and standard deviation
I have a set of % score values (e.g. 88%, 94%, 82%, 67%)
I would like to know if there is a relatively simple formula that can be used to calculate the AVERAGE DEVIATION from 100%, as opposed to the AVERAGE DEVIATION from the mean, which is what the excel function =AVEDEV will return.
E.g. The Average Deviation from the mean for the the above set of values is 8.25%, whereas the Average Deviation from 100% is 17.25%
I can create a complex manual formula which sums absolute values of the variation from 100% of each score, and then divides by the count total of the number of scores, however this is flawed for several reasons, including the fact it is very time consuming when used across a large set of scores, and it is corrupted when a non score exists in a cell (some of the 'scores' may be '-', in which case they should be ignored and not included in the calculation of the average deviation from 100% by treating as a 0% score (and a deviation of 100% from 100%).

I have a simple count formula which is suppose to be absolute.
=COUNT($L5:$V5) and works till I add a column via a macro.
Macro adds a new column at column M then inserts data.
My problem is when I check the formula after macro it changes to
=COUNT($M5:$W5) I thought using the $ sign means Don't change?
how to get either the absolute row or the absolute column of a cell.
Suppose the active cell is H27.
If we use:
ActiveCell.Address
we will get $H$27
How can we get either $H or $27 only assigned to a variable let it be MyVar.
Please keep in mind that converting the $H$27 to a string and then making string manipulations is not accepted, unless of course it's the only way to go.
Also it would be nice if I get answers on how to get the relative address column/row portions only, too. Like H or 27.
Another tip is that using .Column returns a number, not a letter.

View 4 Replies View RelatedI'm looking for the proper way of determining the success of a forecast over time.
Forecast ranges from -25% to +25%.
I don't want an average, as it would return a 0% deviation over 2 periods.
I don't want a standard deviation as it would be deviation from an eventual mean greater than 0.
I want the result of the above to say that my average deviation is 25 basis points. Meaning I'm either high or low by 25 points or that I'm "usually" off by +/- X%
Just like sumif and averageif, is there a standarddeivationif?

So this is what I am trying to do.
I have a list of about 1000 stock price returns in the following format
jan 1 2008 .033

What I want to do is calculate in VBA a moving 3 day standard deviation of returns. So I want the first calculation to include jan 1 - jan 3 and place the answer in the cell to the right of jan 3 return. Then move down 1 row and calculate the standard deviation using jan 2 - jan4 and place the answer in the cell to the right of jan 4 return...and so on until the last cell.
i'd like to calculate the standard deviation of different items all in the same database
If this would be the database:
a 1
a 2
b 9
a 6
b 5
b 3
c 2
c 5
a 7
Than this would be the result:
item a 2.55
item b 2.49
item c 1.50
I succeeded in doing this via a pivot table but i want to create a calculation as the result should be part of other data in another sheet.
The spreadsheet below shows the Date (Column A), Percentage (Column B), and Standard Deviation (Column C). What I would like is a macro that finds the standard deviation for all percentages of a given date, and for the output to be placed in the first cell of Column C of that given date. If a cell in Column C is not the first for a given date I would like for it to be blank.
Date Percentage Stan Dev (Output) 8/19/09 26.75% 0.77% 8/19/09 26.79%
8/19/09 28.14%
8/19/09 26.57%
8/19/09 26.40%
8/19/09 25.54%

I was wondering what the best way to create a standard deviation graph was? I have a single row of numbers and need to make a stadard deviation graph.
I read somewhere that the analysis toolpak would be useful for this but having installed it i'm not really sure what to do next.
I wonder if is posible to discover following:
Who modified the cell from various users.
After that how many cells from xls fiile were modified by one user and how many by another user.
I have an excel spreadsheet with multiple file names (including file path) listed in a column. I have to update other files using these 'underlying' files. So each cell has the file path and file name (i.e. Q:FolderFile Name.xls). I would like to have the adjacent cells indicate the last modified date for each file. This saves me time from looking for the last modified date manually across different folders in my servers to see if the 'underlying' file has been updated, which I would need in order to update my other files.
So this function would be something like "get last modified date based on file path". I will need step by step instructions as I am not very familiar with VBA.
Example:
A B
1 Q:Folder1File name1.xls 2/10/2012
2 X:Folder2File name2.xls 12/1/2011
I am sure this is easy but i cant for the life of me find the code for this:
I am trying to have a MSG Box popup after opening a file and it displays the date the current file was last modified with an "OK" button on it to close the box.
I have a number of excel files in a directory that require me to take action after a file has been saved. What I want to do is create a macro that will look to each file and retrieve its 'modified date', then put that into a spreadsheet. What would be ideal is to create a User Defined Function to look at the last modified date of a file in the cell next to it (I have the files names in a spreadsheet as a hyperlink).
View 2 Replies View Relatedi need simulate data in 10 cells with a fixed standard deviation and a fixed mean
Example: Simulating the laptime for a runner where the mean should be 50 and the standard deviation 5,
I tried typing
=50+5*RAND()*(-1^(RANDBETWEEN(1;2)))
That gives me a mean close to 50 which is good but th standard deviation is no where near 5.
I have a dynamic range that I need to be able to calculate the standard deviation for. The dynamic range sometimes has blank cells and #N/A cells which I do not want included in the calculation. However, there are sometimes cells with the number 0 in it (instead of blank) which I do want to include. I have come up with an array formula, but the standard deviation it calculates is not correct. The formula is:
=STDEV(IF(ISNUMBER(A3:A20000)*ISNUMBER(A3:A20000),1,0)). *This is an array formula calculated by pressing CTRL+SHIFT+ ENTER. The number it calculates is 0.43, however, this is incorrect. If you just calculate the standard deviation of the actual data points in excel (cells A138:A5055 in this case) : STDEV(A138:A5055), it returns 0.17. This is the correct standard deviation.
