A worksheet that gets students to estimate the mean of the UK's score at the Eurovision Song Contest to date - quite topical for the moment! Differentiated so at first students get given the table to estimate the mean and the data is grouped for them. Further examples require students to make their own tables.

For students that are struggling with changing the subject and inverse operations, these functions machines might help make the topic clearer.

This resource can be laminated and cut out. Give each student an event and ask them to come to the board and blu tack their event on the probability scale (that can be drawn/ projected onto a whiteboard). You can do this in pairs or with individuals. After this has been done, choose some of the events to discuss where they should go on the scale.
