Line Graphs

​What do you notice about the two graphs?

What’s the same? What’s different?

• Data you can count with whole numbers

• Impossible to divide into parts

• Examples:

  • Number of people

  • A store's inventory of an item

  • Questionnaire data

  • Points in a game

• Data you can count with whole numbers

• Impossible to divide into parts

• Examples:

  • Number of people

  • A store's inventory of an item

  • Questionnaire data

  • Points in a game

• Data that is measurable

• It changes over time

• Examples:

  • A person's weight or height over time

  • The amount of money a store earned

  • Temperature

​We can use a line graph to represent continuous data.

​We can use a series of points to represent discrete data.

(don't connect the points!)
