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.

There is no standard formula. Different employers use different methods.
the formula for standard form is Ax+By=C
%E= d/L
it is a piece of crap that rots and standard form is some kind of addition of hard freaking nonsense.

addition
The standard formula is A = v/t With slight formula manipulation you get At = v
(actual time * standard rate) - (standard time * standard rate)
