Question

Find the mode
(Family size/1-3/3-5/5-7/7-9/9-11)
(frequency/7/8/2/2/1) ​

Answer 1

Step-by-step explanation:

Class. frequency

1-3. 7

3-5. 8

5-7. 2

7-9. 2

9-11. 1

Model class(Highest frequency) is 3-5.

Then,

L=3

h=2

f0=7

f1=8

f2=2

Therefore,

Mode =L+(f1-f0/2f1-f0-f2)×h

=3+(1/7)×2

=3+0.28

=3.28
