How do I read a bar graph?

Bar graphs are a visual way to represent data using rectangular bars of different heights. In South Africa, Grade 7 students learn about data handling and graph interpretation in their math curriculum. To read a bar graph, start by identifying the categories or items being compared on the x-axis. Then, look at the height of each bar on the y-axis to understand the quantity or value being represented. Finally, compare the heights of the bars to analyze the differences or trends in the data. With practice, students can easily interpret and draw conclusions from bar graphs.
