Draw a histogram for the following frequency distribution:
Age (in years) | Below 2 | Below 4 | Below 6 | Below 8 | Below 10 | Below 12 |
No. of children | 12 | 15 | 36 | 45 | 72 | 90 |
Solution:
First convert the given cumulative frequency into frequency distribution table:
Age (in years) | c.f. | f. |
0-2 | 12 | 12 |
2-4 | 15 | 3 |
4-6 | 36 | 21 |
6-8 | 45 | 9 |
8-10 | 72 | 27 |
10-12 | 90 | 18 |
represent age on x-axis and number of children on y-axis :
