Pictographs

  • In a pictograph each picture stands for an amount. The key says what one picture is worth.
  • Key: 1 picture = 1 learner. A row with 6 pictures = 6 learners.
  • Count the pictures in each row and compare: the row with the most pictures is the most popular.

  • A pie chart shows data as slices of a circle. The whole circle is all the data (the whole group).
  • Half of the circle = ½ of the group; a quarter of the circle = ¼ of the group.
  • Example: 40 learners. Half choose soccer: ½ of 40 = 20. A quarter choose netball: ¼ of 40 = 10. The other quarter choose cricket: 10.
  • The biggest slice is the most popular.
