The standard deviation. of a series of measurements which includes at least 6 independent trials may be defined as follows. If we let . x. m be a measured value, N. be the number of measurements, < x > be the average or . mean. of all the measurements, then . d. is the . deviation . of a value from the average: d = x. m-< x > and the standard ...
