## 3. Interval

Interval: has values of equal intervals that mean something. For example, a thermometer might have intervals of ten degrees.

**Examples**:

- Celsius Temperature.
- Fahrenheit Temperature.
- IQ (intelligence scale).
- SAT scores.
- Time on a clock with hands.

## 4. Ratio

Ratio: exactly the same as the interval scale except that the zero on the scale means:does not exist. For example, a weight of zero doesn’t exist; an age of zero doesn’t exist. On the other hand, temperature is not a ratio scale, because zero exists (i.e. zero on the Celsius scale is just the freezing point; it doesn’t mean that water ceases to exist).

**Examples**:

- Age.*
- Weight.
- Height.
- Sales Figures.
- Ruler measurements.
- Income earned in a week.
- Years of education.
- Number of children.

*It could be argued that age isn’t on the ratio scale, as age 0 is culturally determined. For example, Chinese people also have a nominal age, which is tricky to calculate.
