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

Explanation:

Ratio-level data is the highest level of measurement. It inherits all properties of interval-level data (which has ordered categories with consistent intervals between values). Unlike interval data, ratio data has a true, meaningful zero point (a value of 0 indicates the absence of the measured quantity), which allows for meaningful ratios between two measurements (e.g., 10 kg is twice 5 kg). Qualitative data with no natural ordering is nominal-level data, not ratio-level.

Answer:

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