Question

In the tables given below, class-mark and frequencies is given. Construct the frequency tables taking inclusive and exclusive classes.

Class width  Frequency
5 3
15 9
25 15
35 13

Solution

In the tables given below, class-mark and frequencies is given. Construct the frequency tables taking inclusive and exclusive classes.

Class width  Frequency
5 3
15 9
25 15
35 13

We have, class size = 15 - 5 = 10
Since, the lower limit of class-mark 5 = 5 - `10/2` = 0
and the upper limit = 5  + `10/2` = 10.
So, the exclusive frequency table is given by:

Class width  Frequency
0 - 10 3
11 - 20 9
21 - 30  15
31 - 40 13

Also, the inclusive frequency table is given by:

Class width  Frequency
0 - 10 3
11 - 20 9
21 - 30  15
31 - 40 13
  Is there an error in this question or solution?
