Answer:
Given : 31, 23, 19, 29, 22, 20, 16, 10, 13, 34, 38, 33, 28, 21, 15, 18, 36, 24, 18, 15, 12, 30, 27, 25, 20, 17, 14, 32, 26, 25, 18, 29, 24, 19, 10, 11, 22, 15, 17, 10
To Find : Form a grouped frequency distribution by inclusive method taking 4 as the magnitude of class intervals.
Solution:
Arranging in order
10 10 10 11 12 13 14 15 15 15 16 17 17 18 18 18 19 19 20 20 21 22 22 23 24 24 25 25 26 27 28 29 29 30 31 32 33 34 36 38
inclusive class intervals. - Lower and upper both limits are included for data
Class Frequency
9 - 12 5 ( 10 , 10 , 10 , 11 , 12)
13 - 16 6 ( 13 14 15 15 15 16 )
17 - 20 9 ( 17 17 18 18 18 19 19 20 20 )
21 - 24 6 ( 21 22 22 23 24 24)
25 - 28 5 ( 25 25 26 27 28 )
29 - 32 5 ( 29 29 30 31 32 )
33 - 36 3 ( 33 34 36 )
37 - 40 1 ( 38 )
Total 40
