Determine whether the following data could be represented in a histogram. If not, state your reasoning.
Age Frequency
25-29 7
30-39 6
40-54 8
55-74 2
75-99 4
Solution
Given that
To draw histogram, we first prepare the frequency distribution
with boundary points, with central value of each class
Class | Lower | Upper | Frequency f |
25 - 29 | 24.5 | 29.5 | 7 |
30 - 34 | 29.5 | 34.5 | 6 |
35 - 39 | 34.5 | 39.5 | 8 |
40 - 44 | 39.5 | 44.5 | 2 |
45 - 49 | 44.5 | 49.5 | 4 |
