Line Graphs

A line graph is a way of showing continuous data.

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).

Using line graphs example

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.
