Mean for Grouped Data For grouped data, we can find the mean using either of the following formulas. Direct method: \(\begin{array}{l}Mean, \overline{x}=\frac{\sum_{i=1}^{n}f_ix_i}{\sum_{i=1}^{n}f_i}\end{array} \) ...
For grouped data, mean, x̄ = Σfx/Σf where, f = frequency of each class x = mid-interval value of each class What is Mean Formula for Grouped Data? The mean formula to find the mean of a grouped set of data can be given as, x̄ = Σfix/iΣfi, where, x̄ is the ...
= antilog 8.925/5 = antilog 1.785 = 60.95 therefore the g.m of the given data is 60.95 question 3: find the geometric mean of the following grouped data for the frequency distribution of weights. weights of ear heads (g) no of ear heads (f) 60-80 22 80-100 38 100-120 45 120...
We know that the G.M for the grouped data is GM = Antilog (∑ f log xᵢ) / n GM = Antilog (324.2 / 160) GM = Antilog (2.02625) GM =106.23 Therefore, the GM =106.23 Answer: Therefore the geometric mean of the given data is 106.23 Practice Questions on Geometric Mean Q1. After...
