This document provides information about bar graphs:
- Bar graphs use bars of equal width to show frequencies of different classes or groups. They can show relationships between two or more items.
- The key parts of a bar graph are the title, horizontal and vertical axes labeled with intervals, and bars whose heights represent recorded frequencies.
- An example bar graph shows the favorite movie of 30 grade 7 students, with the most popular being at 25 students and the least being at 5 students.
