Line Graphs
Maths: Year 3 & 4 National Curriculum, topic 8.1.3
Line Graphs
A line graph is a way of showing continuous data.
Continuous data
- Continuous data is data that can be any number.
- People's heights are an example of continuous data because your height can be any number.
- Shoe sizes are NOT continuous data because your shoe size CANNOT be any number (e.g. you can't have size 7,431 feet).
Line graph example
- This line graph shows the rate of growth of a sunflower.
Using line graphs
- You can use a line chart to find out information.
Using line graphs example
- You can see that the sunflower grew to 20 cm within 31 days.
- You can tell this because 20 cm is our highest point and our graph shows that it was measured over 31 days.
