Arithmetic mean is a measure of central tendency of a set of values of a variable and is obtained by dividing the sum of the values of the variable by number of values included in the sum. Mathematically, if x1, x2 , …, xn be the n values of a variable x and (read as x […]
A.M.
Relation among A.M., G.M. and H.M.
(a) For any two positive numbers. A.M. ≥ G.M. ≥ H.M. Proof : let x1 and x2 be two the two positive numbers. therefore their, (b) for pair of positive number A.M. × H.M = G.M.2 Proof : let positive number be x1, x2. therefore, Example: The A.M. and G.M. of two number are […]
