Unformatted text preview: Interval-Quantitative, measurably equal distances between observations. Lacks a true zero point (zero is just another point on the scale). Ex: temperature: we measure it at below 0. Each degree is equally far apart. 0 degrees does not mean a lack of temperature, it's just another point on the scale. What does that mean?
