Understanding different types of data is really important when picking the right graph in Year 8 math.

1. Types of Data:

   • Categorical Data: This is about categories. For example, colors or types of fruit.
   • Numerical Data: This is about numbers. It can be:
     • Discrete (like counting the number of students)
     • Continuous (like measuring someone’s height)

2. Graphs for Different Data Types:

   • Bar Graphs: Great for categorical data. They help compare different groups easily.
   • Histograms: Best for continuous numerical data. They show how often something happens.
   • Line Graphs: Perfect for showing continuous data over time. They help us see trends.

3. Example of Statistics:

   • Let’s say we survey 200 students. Using the right graphs can help us understand differences, like the fact that 60% of students prefer sports over arts. This makes the data much clearer. Picking the right graph can make understanding the information easier by 70%.
