The experimental value, Ex, of a quantity is usually expressed as: Ex = x ±o. This
value gives us the best estimate of the quantity measured. For a normal distribution of
random errors, it is found that the probability that an individual measurement will fall within
one standard deviation of the mean, x ±o, which is assumed to be the true value, is 68%;
for x ±20, it is 95.5%; and for x ± 3o, it is 99.7%. This justifies our discarding any
measurement "off" by more than 30 from the arithmetic mean as a mistake or not properly
measured. They are not within the range of normal errors.
