A fitness coach records the number of hours a group of athletes trains each week. The data is grouped into ranges:
- 0-2 hours: 3 athletes
- 3-5 hours: 7 athletes
- 6-8 hours: 10 athletes
- 9-11 hours: 5 athletes
- 12-14 hours: 2 athletes
What type of graph would best represent this data to show the distribution of training hours among the athletes, and why?
A histogram is the best choice because it displays the frequency of data within specified ranges (intervals), making it easier to see how many athletes fall into each range of training hours.
