32 33 30 31 |
31 |
The correct answer is Option 4: 31
The Modal class is (30-35) as it has the highest frequency of 7. Mode = L + [D1/ (D1 + D2)] * h Where, L = lower limit of the modal class D1 = difference between the frequency of the modal class and the frequency of the class preceding the modal class (ignoring signs). D2 = difference between the frequency of the modal class and the frequency of the class succeeding the modal class (ignoring signs). h = class interval of the distribution. Putting the values in the formula of mode, D1= 7-6= 1 D2= 7-3 = 4 h= 5 Mode = 30 + [1/ (1 + 4)] * 5 = 30 + 5/5 = 31 |
