Quizplus · Accepted Answer

Money given to the tsunami relief effort can be measured at the ratio level of measurement because it has a true zero point (i.e. it is possible to give no money at all) and the differences between values are meaningful (i.e. someone who donates $50 has given more than someone who donates $20).
