Question

Find mode of the following data.

C - I 1 - 3 3 - 5 5 - 7 7 - 9 9 – 11

F 7 8 2 2 1.​

Answer 1

Step-by-step explanation:

CI f

1-3 7 Modal Class(class with highest frequency)

3-5 8 3-5

5-7 2 l = 3, h = 2, f0 = 7, f1 = 8, f2 = 2

7-9 2

9-11 1

Mode Z = l + (f1-f0/2f1-f0-f2)h

= 3 + (1/7)2

= 3 + 2/7

= 3 + 0.28

So, Z = 3.28
