Questions like “is someone who earns over $150,000 a year rich?” or “how much does the average Australian earn?” seem as though they should be easy to answer. But in practice both questions are tricky.
For the latter you need to figure out whether you mean the “typical” Australian or the mean; whether or not to include only people who are employed, and so on.
