the ratio between two measures is meaningful.
the measures can be ranked in order.

the distance between values is a known unit of measure.

Explanation:

• Ratio-level data has meaningful ratios between measures.
• Ordinal-level data can be ranked in order.
• Nominal-level data is only countable.
• Interval-level data has consistent, known units of distance between values, with no true zero point.
