Bar Graphs

The video tutorial explains how to compare population data using bar graphs. It highlights the limitations of tables and introduces bar graphs as a more effective visual representation. The tutorial covers the components of a bar graph, including titles, labels, scales, and bars. It provides examples of both vertical and horizontal bar graphs, demonstrating how to interpret data such as population figures and student scores. The video emphasizes identifying the longest and shortest bars to determine the largest and smallest values.
