Answer 4

To calculate the standard deviation of those numbers:

•1. Work out the Mean (the simple average of the numbers)
•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 and you are done! (:
