Question
Solution
Model class = 25 - 30 Lower limit of the model class (L) = 25 Frequency of model class (f1) = 11 Frequency of preceeding model class (f0) = 9 Frequency of next model class(f2) = 10 h = 5 Mode = L + {(f1 - f0 ) / ( 2 f1  - f0  - f2) } h Mode = 25 + {(11 - 9)/22-9-10 } 5 Moode = 25 + 3.33 Mode = 28.33 ans.Â
