Three "real life" situations where calculating an average or range would help with decision making.
I use this resource as a starter exercise to prompt discussion about the different averages (and range) and to help students realise there is a point to having the different measures.

Students shouldn’t be told how to answer the questions but can be prompted by asking “what could you work out that would help you to decide?”
There are no “right answers” here (although some are better than others). These questions are intended to promote discussion about the different measures that can be calculated and which situations they are best applied to. It also helps to answer the question of why do we need to learn 3 different ways of doing the “same” thing.

Just what I needed, thank you - getting students to think about which average and why :-)
