the process is tediuos at best ...

find the mean by adding up all the values, and dividing that by how many numbers there are

this in turn can be used to find the standard deviation ... which in itself is a nightmare to do by hand

subtract the mean from each value, and square the results, add up the squares, and divide by how may numbers there are (if its a population); OR divide by one less than that (if its a sample)

then take the square root of that result for you standard deviation ...
