A visual representation for bivariate data. It can be useful when determining the nature of the relationship between the two variables

Constructing scatter graphs by utilising technology

Maths

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

Graphical representations of data

A circular graph where sectors represent different groups proportionally

A graph consisting of bars  to representing the frequency of objects or groups

A graph consisting of pictures to represent the frequency of objects or groups

A graph consisting of two axes to visually represent bivariate data
