Sample: the first question, solved
A scatter plot shows a strong positive relationship between the number of firefighters at a fire and the amount of damage. Do more firefighters cause more damage?
📘 Worked solution
✓No - larger fires require more firefighters and cause more damage; fire size is a confounding variable behind both.
And one from the hard end
Compare a well-made scatter plot (accurate scales, clear labels, source noted, no deceptive trendline) to a misleading version of the same data, explaining how the misleading version could distort conclusions.
