The monthly income of 100 families are given as below


Calculate the modal income.


In a given data, the highest frequency is 41, which lies in the interval 10000 - 15000.

Here, l = 10000,fm = 41,f1 = 26,f2 = 16 and h = 5000






= 10000 + 15×125


= 10000 + 1875


= 11875


Hence, the modal income is Rs.11875 per month.
