Quizplus · Accepted Answer

A ratio scale is the most appropriate because it has a true zero point (meaning that there are no legs on a centipede) and each unit of measurement is equal (each leg is counted as one unit). Nominal scales involve naming or categorizing things, ordinal scales have a ranking order but no equal intervals, and continuous scales involve numerical measurements with infinite possible values.
