Arithmetic mean refers to the average amount in a given group of data. There are many ways to calculate arithmetic mean like direct method where all the data are added up and then .
How to Calculate Mean of Grouped Data? How to Calculate Arithmetic Mean of Grouped Data?
To determine the arithmetic mean of grouped data, three methods are available (Direct method, Short-cut method, and Step-deviation method). Arithmetic mean grouped data - information. Formula used to calculate the arithmetic mean of the point distributing series (grouped data): ¯x = f 1⋅x1 +f 2 ⋅x2 +⋯+f n⋅xn f 1 +f 2 +⋯+f n = ∑f x .
Calculate Mean by the Formula Mean = ∑xi i fi i / ∑fi i. Where fi i is the frequency and xi i is the midpoint of the class interval. May 01, · Formula for finding the Arithmetic mean of n observations is: Arithmetic mean=ΣX/n Where n is the number of observations.
