Students learn how to illustrate and interpret a set of continuous data using bar charts. Population pyramids are introduced later in the lesson to add a real life context.At the start of the lesson students recap interpreting composite bar charts by considering the age distribution of male and female teachers. In the plenary students discuss the differences between two population pyramids showing the age ranges of people in the United States in 1950 and 2016.
