View 8 Replies View RelatedI'm getting a time data on the format "0h 00m 00s" but I can't convert it to a standard "00:00:00" format to properly handle it and I'm not so Excel savvy. I already tried looking for something on google but the formulas for similar issues "0h 0s" or "0d 0h 0h" are not working (I can't find a way to adjust them). For example: I'm have the following data on G3:
0h 37m 52s
and I'm using the following TIME/FIND formula:
=TIME(FIND("h",G3),FIND("m",G3),FIND("s",G3))
but the outcome is "2:06:10" instead of "0:37:52"
I use Excel 2000.
I want to hide all toolbars when I work.
I know how to hide them during a session, but when I exit and reboot Excel, the "standard" toolbar always returns.
Is there some way to hide the "standard" toolbar permanently?
I have a set of data and need to get Stdev 1, Stdev 2 and Stdev 3 but i honestly not sure what are those. I have attached the file : stdev.xlsx
View 4 Replies View RelatedI am trying to learn VBA and started reading Wallenbach's book and I thought the best way to get up to speed fast was to work on some real problems.
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
jan 2 2008 .01
jan 3 2008 -.002
jan 4 2008 -.0033
jan 5 2008 .04
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%
8/19/09 26.61%
9/16/09 36.54% 3.04% 9/16/09 37.27%

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 want to include a legend to a bubble chart in the folowing format: the smallest bubble in this legend should represent values between A and B, the second (somewhat bigger bubble) should represent values between B and C,and so on. Is it possible to produce a standard legend in a bubble chart?
View 2 Replies View RelatedI'm a moderate user of excel with some experience but need help creating a specific if statment.
I have a column "A" that shows dates formated like this: 060115 (January 15, 2006). Because excel does not recognize this as a valid numerical date I need column B to show what year the date falls under. To complicate it I need it to reflect a seasonal year from April 1 YYYY, to March 31, YYYY.
So here's an example. Say I have a date in column "A" of 050612 (June 12 2005). I need column "B" to look at that date and determine if it's >040105 and <033106 and return a result of "2005". I then need the formula to calculate an answer for up to 5 years worth of returns.
how to set up this type of =IF statement?
I don't how I did it, but my standard toolbar is gone in the Visual Basic Editor. I cannot figure out how to get it back.

How to change color of the cells that are between the average and 1 standard deviation. The rules that I applied are 1. 1 standard deviation above change to Yellow, 2. 2 standard deviation above change to Orange, 3. 3 standard deviation above change to red 4. equal and below change to green. However when I apply these rules then everything within the average and 1 standard deviation remains white. I have attached my excel file.
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.
The problem is that Excel always stop when it found a condition being "true".
I have table with a range of percentages and a "standard percentage value"
I now want to highlight all percentages into three traffic light colours depending on whether they are:
1. 80% greater or less than the standard value (RED)
2. 50% greater or less than the standard value (ORANGE)
3. If else then they are ok (GREEN).
in addition it would be nice to have those boxes which display 0 in blue.
I have a sheet of data in which Column A contains a list of sales agents names and Column B contains their results against their KPIs. All the data is terribly skewed due to new metrics so I have been tasked with attributing 'ranking band' to their performance, i.e. very low, low, medium, high, very high.
I have calculated the average and standard deviation for the list of data, but now I need to calculate which ranges will fall under which ranking band, e.g. very low is less -18%, low is greater than 18% but less than 80%, etc.
I also need to come up with a nested if statement next to each of the sales agents so it returns what ranking brand they are on based on their performance. Sample sheet attached. EDIT - attachment on post #4.
So this forum has helped me in the past develop a standard deviation that removes max and min from the data set.
=STDEV(LARGE(E5:AB5,ROW(INDIRECT("2:"&COUNT(E5:AB5)-1))))
Would if be possible to adjust this formula to ignore N/A's?
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.
In my stock list I am trying to now sort non standard formats of numbers. They are electronic values starting fro "0R", "1R2", "1K", "1k5" and then onto numbers like 1M and 1M6
How do I set up a sort into ascending oredr numbers like this
I am trying to calculate the Standard Deviation of an array. However, to populate the array, I have the following:
Count Number 1 Count Number 2 CountNumber 3
1 100 2 200 3 300
For example, this above means that there are 1 100's, 2 200's, 3 300's. I would ideally like to populate an array that is {100,200,200,300,300,300} based on those 6 columns that provide a count and a number. Then, I would like to calculate the standard deviation based on those (in this case it is 74.5).

When I hit the print button on the Standard Toolbar, I want my printer to print only the number of pages specified on my worksheet which I previously entered into Cell A1.
Is there a formula or something I can use for this?
I need the Standard Print button to print only the number of pages I've entered in Cell X1 when I click it, (and if I haven't entered any value in Cell X1, nothing should be printed.)
Now, where this gets tricky, is that I still want to be able to override this automatic number printing if I want, by selecting 'File/Print...' from the menu and choosing a different number of pages to print.
I have a file, and I want to put in the standart deviation, over 100 points a time. So =C2:C102, next will be C3:C103 etc, but only if there are values in the Easting column. I ID the columns, but something is wrong about by code, it put's like $ for the row and column.

I use manual selection (e.g. =STDEV(B1:B3, B5:B6, etc...) that covers the 40
consecutive rows. B4 here is zero so I did not select it.
My rows is getting bigger and bigger, how could I formulate this?
