Ideas in this flowchart
- The measurement scale determines which manipulations and interpretations are valid.
- Quantities are classified into four measurement scales.
- Nominal quantities represent categories.
- Ordinal quantities represent ranked values.
- Interval quantities represent differences on a scale without a natural zero.
- Ratio quantities have a meaningful zero.
- Celsius temperature is interval-scaled, so 2°C is not twice 1°C.
- Kelvin temperature is ratio-scaled and supports such comparisons.
