Standard Dev For A Whole Column, 100 Points A Time
Feb 17, 2009
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 need a simple formula to convert standard time (1:05pm) into military time (13:08).
I've read through several posts, but all I've found is reformatting or time subtraction type information. The reformating works to an extent, it gives me the hours in military but the minutes stay standard.
Basicly, all I need is:
Cell A1 = 1:05 p Cell B1 = formula that shows/converts 1:05 p as 13:08
I'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:
Is it possible to convert the following data to an Excel-recognized time format (easily, as I have numerous million-row files with time data like this). Some actual data is below with what it should be in parentheses.
I'm copying data from another source to excel, and for certain date entries they come as text in the following format "On 14 May at 8:00". Is there anyway to convert multiple entries like this into a standard date format? With or without time is fine - just the date will do.
Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value? eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm. Other than creating a table and using a vlookup function
I am trying to calculate the duration between two times on different days.
For example - I want to know the number of days/hours/minutes/seconds between 25th Feb 2009 20:00 & 27th Feb 2009 22:00.
I am sure that the key is how I enter the data into the cells and how those cells are formatted, I just cannot get Excel to see that the times are on different days. At the moment my data is in a raw format with times in one column and dates in another.
I ran across a great article on performing Drive Time Calculations between two addresses. The only problem is that I can not seem to get it to work properly. Here is a link to the article cause I want full credit to be given to the person that created it.

Here are the steps I have taken so far.
1. Downloaded Microsoft Internet Transfer Control reference (msinet.ocx) per [URL]
2. Registered the msinet.ocx
3. Selected Microsoft Internet Transfer Control as a Reference in Visual Basic.
4. Copied the custom function for DriveTime into a module.
5. Went to sheet that contained addresses (Column A contains PointA, Column B contains PointB)
6. In C2 I entered the formula =DriveTime(A2,B2)
7. After entering the formula I get a error (#VALUE)
I have a number of time data elements of different recordings that i would like to be able to use one formula in one cell and have it give me to total time. For example:
00:03 00:55 00:47 00:05
All in one cell (i.e., not having each data point in a cell), I would like to have the formula tell me that these four recording times equal 00:01:48 (i.e., 1min 48 sec).
I have a set of data points with date and time shown in the picture. I need to take out all the data point that are at the 30 min interval. Meaning I only want to have the data points hourly only. What can I do to remove the :30 minute datas.
I have tried the find option typing In :30 and getting all the points but then have to replace, which I do not want to do. Need to remove them so they do not show up on the trends ( graphs) I made for them.
This is for excel 2007.
Seems I can't get picture up on the ipad, so the data points look like this
I run data sets and use standard deviation frequently but will often times have an issue with the formula. For instance in the following example I use the standard deviation function for the $/Acre column and it returns a value, but using the same data set to try to get a value for the $/WFF column gives the #DIV/0! error message.
I want to calculate standard deviation for about 5~22 cells (number is not the same every time) in a column before "#N/A" appears after the last valid number. How can I do that?
I want to enter any thing in column (A) and then the date & time automaticaly put in column (B) enter any thing in (A1), the date & time entered in (B1) automaticaly enter any thing in (A2), the date & time entered in (B2) automaticaly
I 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.
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%
