Question

More of the following table is

Class : 0-5 5-10 10-15 15-20 20-25

Frequency: 25 15 8 3 2​

Answer 1

What is frequency.... I can't understand

Answer 2

Step-by-step explanation:

Here N= 66.

Therefore N/2=33, which lies in the interval

10-15

So,the lower limit of median class is

10.

The highest frequency is 20,which lies between the interval 15-20.

Therefore the lower limit of model class is

15.

so,the required sum is 10+15=25
