Question

Q13. Find the mode from the given data: (2017)
Class Frequency
0-5 5
5-10 7
10-15 9
15-20 18
20-25 16
25-30 15
30-35 6
35-40 3

Answer 1

Answer:

Here, we can see class 10−15 has maximum number of frequency.

∴ Modal class =10−15

Then we have,

l=10,f

0

=3,f

1

=10,f

2

=1 and h=5

Since,

Mode=

=10+2.18

=12.18

∴ Mode=12.18

Hence, this is the answer.
