To install the program simply send the file DVIATION.83p to your calculator using an appropriate program.  If you do not have a link cable simply type out the program yourself, the souce code is at the bottom.

How to use:

Once you have the program in the calculator simply run the program by pressing the PRGM key, this will give you a list of all the programs in your calculator.  This program needs a little editing before it is ready to use.  Click the left arrow key on the calculator to go over to edit, higlight the name DVIATION and hit the return key.  On the first line type in the Mean Weight.  Make sure that you don't delete the arrow  Move the arrow to the second line and type in the amount of variables that you have (say you have 10 results, type in 10).  Now hit shit and del to quit.  Click the PRGM button once again and highlight the name DVIATION to execute the program.

The first thing it asks you is the Variable of X, type it in and hit return.

The second thing it asks you is the probability, type it in and hit return.

Continue doing so until the program stops, and displays your resutts (the Standard Deviation).
