Given:
The data values are 13, 6, 12, 9, 11, 14, 2, 8, 18, 16, 9, 12, 17, 11, 19, 6, 7, 12, 22, 21, 18, 1, 8, 12, 18.
To find:
The frequency distribution table for given data values by using the class intervals 0-5, 5-10,..., and draw a histogram.
Solution:
The frequency distribution table for given data values is:
Intervals Data values Frequency
0-5 2,1 2
5-10 6,9,8,9,6,7,8 7
10-15 13,12,11,14,12,11,12,12 8
15-20 18,16,17,19,18,18 6
20-25 22,21 2
To draw the histogram, intervals must be represented on the x-axis and frequencies represented on the y-axis as shown below:
