Learning activity

• Ask students to record in their books two items of data: their height and their gender. This should be recorded as a set of class data.

• Discuss with the class whether there is any correlation between the two sets. Are boys taller than girls?

• Graph this data as pairs of x and y values to obtain a range of points. Is there a line of points? What does this tell us? Is there a correlation?

Learning outcomes

To decide whether there is any correlation between the two sets of data.

Extension work

Choose other pairs of data and see if there are correlations.
