In a school, 46 students of 9th standard, were told to measure the lengths of the pencilsin their compass-boxes in centimeters. The data collected was as follows.
16, 15,  7, 4.5,   8.5,  5.5,  5, 6.5, 6, 10, 12, 13, 4.5,  4.9,   16,  11, 9.2,   7.3,  11.4,  12.7,  13.9,  16, 5.5,  9.9,   8.4,   11.4,  13.1,   15,  4.8,   10,  7.5,   8.5,   6.5,   7.2,   4.5,   5.7,   16,   5.7,   6.9,   8.9,   9.2,   10.2,   12.3,   13.7, 14.5,   10
By taking inclusive classes 0-5, 5-10, 10-15.... prepare a grouped frequency distribution table.

Solution

Given:
In a school, 46 students of 9th standard, were told to measure the lengths of the pencilsin their compass-boxes in centimeters. The data collected was as follows.
16, 15, 7, 4.5, 8.5, 5.5, 5, 6.5, 6, 10, 12, 13, 4.5, 4.9, 16, 11, 9.2, 7.3, 11.4, 12.7, 13.9, 16, 5.5, 9.9, 8.4, 11.4, 13.1, 15, 4.8, 10, 7.5, 8.5, 6.5, 7.2, 4.5, 5.7, 16, 5.7, 6.9, 8.9, 9.2, 10.2, 12.3, 13.7, 14.5, 10
The grouped frequency distribution table for the given data is as follows:

Class Interval Tally Marks Frequency
0-5 5
5-10 20
10-15 15
15-20 6
  Total 46
