Question

Represent the following data by histogram :
Price of Sugar
Number of Weeks
(per kg in ;)
18-20
20—22
22—24
24—26
26–28
28–30​

Answer 1

Step-by-step explanation:

max. frequency = 22

so group is = 22−24

so mode = L+

L= lower class boundary of the modal group

f

1

= frequency of the modal group

f

0

= frequency of the class preceding or just before the modal class

f

2

= frequency of the class succeeding or just after the modal class

w= group width

mode = 22+

2×22−8−12

22−8

×2

mode= 22+1.167

mode = 23.167

mode = 23.2
