The level of measurement that includes qualities of the others (nominal and ordinal) and has a fixed zero point is the **ratio** level of measurement.
In summary:
- **Nominal**: Categories without a specific order (e.g., colors, names).
- **Ordinal**: Categories with a meaningful order but no fixed interval between them (e.g., rankings).
- **Interval**: Numeric scales where the difference between values is meaningful, but there is no true zero (e.g., temperature in Celsius).
- **Ratio**: Numeric scales like interval, but with a true zero point, allowing for the comparison of absolute magnitudes (e.g., weight, height).
Hence, the answer is **ratio**.
