Mean formula

Mean Formula

In general sample mean (A.M) or average of n observations x₁, x₂, …, x_n is defined to be the number x such that the sum of the deviations of the observations from x is 0. That is, the arithmetic mean x of n observations x₁, x₂, …, x_n is given by the equation

(x₁ − x) +(x₂ − x) + ^... +(x_n − x) = 0

Hence sample mean formula = x₁+x₂+x₃+…….x_n / n

sample mean formula= sum of elements / number of elements
