Data that can be recorded numerically describes quantifiability—the ability to assign numbers to observations and perform calculations with them. When an index uses numeric components, you can quantify levels, make comparisons, and analyze changes over time. Reliability, validity, and sensitivity are important measurement properties: reliability is about consistency, validity about accuracy to what’s being measured, and sensitivity about detecting small changes. They speak to the quality of the measurement process rather than the data’s numeric nature, which is why quantifiability is the best fit for this question.
