Q10 of 43 Page 293

Select a proper option (a), (b), (c) or (d) from given options and write in the box given on the right so that the statement becomes correct:

(9) The modal class of the frequency distribution given below is



Observe that, from the given data:

The maximum class frequency, here, is 17 and the class corresponding to this frequency is 30 – 40.


So, this implies that,


Modal class = 30 – 40


[∵ modal class in a grouped frequency table can be calculated by corresponding maximum class frequency]


Thus, option (c) is correct.
