Arithmetic Mean |
The correct answer is option 1: Arithmetic Mean $\overline{X}$ = A + (Σd/N) is the formula for calculating Arithmetic Mean by using assumed mean method. Sum of all deviations is taken as Σd=Σ (X-A) A = assumed mean X = individual observations N = total numbers of observations d = deviation of assumed mean from individual observation, i.e. d = X – A |
