The effect of random errors on a measurement of a quantity can be largely nullified by taking a large number of readings and finding their mean. The formula for the mean is, of course, as shown below: Examine the set of micrometer readings we had for the diameter of the copper wire. Let us calculate their mean, the deviation of each reading from the mean and the squares of the deviations from Class practical. This experiment gives a direct measurement of the acceleration due to gravity.

This apparent motion permits distance measurement by parallax. The largest proper motion is exhibited by Barnard's Star which is about 5.9 light years from the Earth. Barnard Star's proper motion is 10.3 arcseconds per year, taking only 200 years to travel the angular diameter of the moon across the sky. The average deviation, = 0.086 cm The standard deviation is: The significance of the standard deviation is this: if you now make one more measurement using the same meter stick, you can reasonably expect (with about 68% confidence) that the new measurement will be within 0.12 cm of the estimated average of 31.19 cm.
