Data Program for Error An P2
** **
You may download the data program or run it directly from the site. Note the following:
The program is in an ongoing process of development and some of the buttons might not work. However the operations you are instructed to perform below have been tested and do work.
When you run the program you might encounter some message boxes at the beginning; these boxes have been inserted to prompt the inclusion of some additional features in the program. If you do encounter these message, you may safely just click through them messages until just the form appears.
The program is easy to use and is very efficient for its purpose. Additional features will be added as needed.
Run the program and click through any extraneous messages. (If necessary you might need to click on the maximize button to maximize the size of the form and make all the buttons visible, but this should not be an issue.)
Delete all information in the textbox (you can use the Clear button near the lower right corner of the box), and copy your TIMER data into the box. You may use either the data you have retained from the TIMER program or the data as posted on your access page (data should be posted if you submitted the program in a timely fashion).
Your data will be in 3 columns. Manually delete all the information except the 30 time intervals, so there are 30 lines each with a single number in the textbox, the number representing the time interval in seconds (if your original data is in a spreadsheet you could just copy the single column corresponding to the time intervals).
Copy and paste these 30 lines into a separate text editor or word-processing program so you can use them again later.
Click on the Mean and Standard Deviation button. A message box will appear asking you to confirm that your data is entered in the necessary format. Then the program will very quickly display the mean and standard deviation of that distribution.

The data program will not download onto my computer...What is the direct website I can go to ? Thanks !

The program was written for the Windows operating system. Since you are using a non-Windows computer, you'll need to perform these operations using an alternative.
The simplest alternative is a spreadsheet, which will easily calculate mean and standard deviation.
You should be able to copy your data into a text file, and open that text file with your spreadsheet. The alternative would be to enter the data one at a time into your spreadsheet, which for 30 data points would be feasible but a bit cumbersome.
I'll also try to post a video later today showing how to perform the other operations using a spreadsheet.
