What questions can we ask? Here are some ideas:
- Does everyone understand the graph? For example, at a cursory (and wrong) glance it might appear as if there were 5 times as many deaths in the USA as there are in the UK, which is reasonable because the population of the US about 5 times that of the UK.
- How many homicides were there in the UK in 2012? [Need to know that the population of the UK is about 60 million.]
- Estimate how many people were killed by guns in the UK in 2012.
- How many people were killed by guns in the USA in 2012? [The population of the USA is about 5 times that of the UK.]
