Choosing the right type of graph for your data is super important in Year 8 math. Here are some easy tips to help you pick the best one:

1. Know Your Data Type

• Categorical Data: This is when your data fits into specific groups. For example, different fruits like apples, bananas, and oranges.

  • Graph Choice: Use a Bar Graph or a Pie Chart for this type of data.

• Numerical Data: This type includes numbers you can measure, like heights or temperatures.

  • Graph Choice: Use a Line Graph to show trends over time or a Histogram for showing how often something happens.

2. Think About Your Goal

• Comparison: If you want to compare different groups, go with a bar graph.
• Trends: If you're showing changes over time, a line graph is the way to go.

Example

Let’s say you have data on how much it rained each month in millimeters. A line graph will show how the rainfall changes from month to month.

But if you want to compare how many students are in different clubs, a bar graph would be better!

By understanding your data and what you want to show, you can choose the best and most interesting graph!
