Standard deviation is a way to describe how the data is distributed around the Arithmatic Mean. It is not a simple formula to calculate, as shown in the links.
addition
There is no standard formula. Different employers use different methods.
%E= d/L
the formula for standard form is Ax+By=C
it is a piece of crap that rots and standard form is some kind of addition of hard freaking nonsense.

the formula for averaging anything is addition of all figures and then dividing by the number of numbers.
The standard formula is A = v/t With slight formula manipulation you get At = v
(actual time * standard rate) - (standard time * standard rate)

The formula for converting American standard to metric standard, for example from degrees Fahrenheit to degrees Centigrade, is subtracting 32 degrees from the temperature and multiplying by 5/9.
