Question

Quizplus · Accepted Answer

The ratio scale is the most appropriate for measuring the speed of an automobile because it has a true zero point and the ratios between values are meaningful. For example, if one car is traveling at 60 mph and another is traveling at 30 mph, the first car is going twice as fast as the second. This type of meaningful comparison is not possible with nominal, ordinal, or interval scales.
