Question

find the mode marks from the following data below 10 15 below 20 45 below 30 90 below 40 102 below 50 120

Answer 1

Mode of Data = 23.125

Step-by-step explanation:

Given Data

Below 10      15

Below 20     45

Below 30     90

Below 40      102

Below 50      120

0 - 10        15

10-20        30

20 - 30      45

30 - 40      12

40 -50       18

Maximum frequency 45 lies in 20-30

Hence mode lies between 20 & 30

Mode = 20  + 10 * ( 45 - 30)/(45 - 30 + 45 - 12)

= 20 + 10 * 15 / 48

= 20 + 3.125

= 23.125

Mode of Data = 23.125
