Answer:
In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean.
To calculate the standard deviation of those numbers:
Work out the Mean (the simple average of the numbers)
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.
Take the square root of that and we are done!
