Question

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

Class width Frequency
22 6
24 7
26 13
28 4

Solution

Class mark Frequency
22 6
24 7
26 13
28 4

We have, class size = 24 - 22 = 2
Since, the lower limit of class-mark 22 = 22 - `2/2` = 21 and the upper limit = 22+ `2/2` = 23
 So, the exclusive frequency table is given by:

Class Frequency
21-23 6
23-25 7
25-27 13
27-29 4

Also, the inclusive frequency table is given by:

Class Frequency
20 - 22.5 6
23 - 25.5 7
25 - 27.5 13
27 - 29.5 4

Disclaimer: The exclusive frequency table can vary from student to student. The "Class width" is replaved by "Class-marks" according to the question.

  Is there an error in this question or solution?
