    Standard deviation is very tedious process, but easy. You must keep track of all data you get or you'll get confused if this is your first time.

    1. Work out the mean

    2. Then for each number: subtract the mean and square the result

    3. Then work out the mean of those squared differences.

    4. Take the square root of that.
