Check Your Understanding

1. What is a grouped bar chart?

Answer: A bar chart with two or more bars per category, shown side by side. It lets you compare multiple things across the same categories — like boys vs. girls favorite sports.

2. When would you use a stacked bar chart?

Answer: When you want to show both the total and the parts that make it up. Each bar is divided into colored sections showing how different parts contribute to the whole.

3. What are the essential parts of every bar chart?

Answer: Title (what it shows), x-axis label (categories), y-axis label (numbers), bars of consistent width, and a scale starting at a clear point.

4. When is a horizontal bar chart better than vertical?

Answer: When category names are long (like country names or full sentences). Horizontal bars give more room for labels.
