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.
