Measurement Scales: Which scale has a true zero point?

Explanation:
A measurement scale with a true zero point allows meaningful ratios between values, because zero truly means “none of the quantity.” This is the ratio scale. It lets you say one value is twice as much as another, three times longer, etc. Height, weight, distance, and age are typical ratio-scale measures since zero means no height, no weight, no distance, or no time. Nominal scales are just categories with no inherent order or quantity. Ordinal scales have order but not equal intervals, so you can say which is more or less but not how much more. Interval scales have equal intervals but lack a true zero, so ratios aren’t meaningful (for example, 20°C is not twice as hot as 10°C).
