An explanation of how to read a simple bar chart to find the popularity of a meal, highlighting the relevance of bar charts in everyday life. It demonstrates how to answer a question by collecting and recording data. It also shows how to represent the data as a bar chart to show results.
This clip could be used to help pupils understand the usefulness of bar charts. This could be achieved by asking pupils to explain why Paul's bar graph is not very useful and then to create their own tally of lunch meals eaten by each member of the class and plot that in their own bar charts. Pupils could then be asked to name the most popular meal and explain how the chart helps them to see this.
