Question

Will the median class and modal class of a grouped data class be different? Justify your answer ​

Answer 1

No, the median and modal class of grouped data can also be same in some cases.

Here we have,

N = 50

Then, N/2 = 50/2 = 25

The cumulative frequency just greater than N/2 is 26, then the median class is 120 - 140.

Also the maximum frequency here is 14, then the corresponding class 120 - 140 is the modal class.

Hence the median class and modal class are the same.
