Answer 1

Given :

वर्ग     : 0-6 6-12 12-18 18-24 24-30

आवृत्ति :  8    10     15     5           6​

To Find :  बहुलक

Mode

Solution:

वर्ग                   आवृत्ति ( frequency)

0 - 6                 8

6 - 12                10

12 - 18              15

18 - 24              5

24 - 30             6

15 is amx frequency hence modal class = 12 - 18

Mode = 12  + 6 * ( 15 - 10)/ ( 15 - 10 + 15 - 5)

= 12 + 6  * 5 / 15

= 12 + 2

= 14

बहुलक = 14
