The marks obtained by 40 students of class IX in an examination are given below: 18, 8, 12, 6, 8, 16, 12, 5, 23, 2, 16, 23, 2, 10, 20, 12, 9, 7, 0, 5, 3, 5, 3, 21, 13, 15, 20, 24, 1, 7, 21, 10, 13, 18, 23, 7, 3, 18,17, 16. Represent the data in the form of a frequency distribution table using the same class size, starting with class interval 0-5.
Answers
Given :
Marks of 40 students : 18, 8, 12, 6, 8, 16, 12, 5, 23, 2, 16, 23, 2, 10, 20, 12, 9, 7, 0, 5, 3, 5, 3, 21, 13, 15, 20, 24, 1, 7, 21, 10, 13, 18, 23, 7, 3, 18,17, 16.
Starting class interval = 0 - 5
To find :
Make a frequency distribution table
Solution :
Class Interval Frequency
0 - 5 7
5 - 10 10
10 - 15 7
15 - 20 8
20 -25 8
Total = 40
