Problem solving with graphical representations of data

In this unit, pupils explore different graphs and charts as a way of presenting data visually. Pupils are introduced to scatter graphs and learn how to construct them in this unit. In the future unit, this understanding is extended to using a line of best fit to allow interpolation

In this unit, pupils interpreted and constructed pie charts based on their understanding of fractions and proportion

In this unit pupils will interpret and construct a range of representations of data including bar charts, pie charts and scatter graphs.

The total frequency for this data set is {{ }}.

True - order from the most favourite to the least favourite topping

False - there is no relevant order to pizza toppings so they can be in any order

If a bar chart was to be constructed for data about favourite pizza toppings in a class, the bars would have a specific order. True or false?

This is an example of a __________ bar chart.

The frequency axis needs to have a suitable scale for the data it is presenting. The scale will go up in {{ }} increments.

Three pupils are discussing this bar chart. Who is correct with their observation?

Which of these numbers are multiples of 15?

A pictogram (pictograph) is a graph consisting of pictures to visually represent the {{ }} of objects or groups.
