Here we have given that
The time spent reading a political blog in a day
Now we want construct the frequency distribution using 5 classes
we get
Now First we create 5 classes
Sr.No
Lower Class LImit
Upper class limit
1
0
10
2
11
20
3
21
30
4
31
40
5
41
50
Now we find the Midpoint
we know the formula
Midpoint =( lower limit + Upper limit) /2
Sr.No
Lower Class LImit
Upper class limit
Frequency (fi)
Midpoint
1

45.5
And
Relative Frequency = ( Frequency/ Total of Frequcncy)
Sr.No
Lower Class LImit
Upper class limit
