Explain the ratio level of measurement.

• The ratio level of measurement is the highest level of measurement where data is measured on a scale that has a fixed and meaningful zero point.

• The ratio level of measurement is a level of measurement where data is measured on a scale that has no zero point.

• The ratio level of measurement is a level of measurement where data is measured on a scale that has a variable zero point.

• The ratio level of measurement is the lowest level of measurement where data is measured on a scale that has a fixed and meaningful zero point.
