which of the following are properties of ratio-level data?
the ratio between two measures is meaningful.
the zero point of the data is meaningful.
it is a qualitative measure with no natural ordering.
it has all the properties of interval-level data.

Explanation:

Ratio-level data is the highest level of quantitative measurement. It inherits all properties of interval-level data (ordered, consistent intervals between values). A defining feature is a meaningful true zero, which allows for meaningful ratios between measurements (e.g., 10 kg is twice 5 kg). Qualitative data with no ordering is nominal-level, not ratio-level.

Answer:

• The ratio between two measures is meaningful.
• The zero point of the data is meaningful.
• It has all the properties of interval-level data.
