    Find the average of what ever you wish to measue.
    Figure the difference for each sample from the average, then square that difference,
    Total the squares of all your samples.
    Find the square root of the total of the squares.

    Google, "Standard Deviation Calculator", there are several listed. Just enter your numbers and it will give you the answer.
