Safrina developed a scale to measure sexist attitudes. It worked such that a person with a sexist attitude score of zero truly had neutral attitude and a person who had a score of 50 had exactly double the score of someone with a score of 25. She created a variable with a(n) scale of measurement.

Ratio variable

Explanation: The ratio variable represents a type of interval scale, however, in the ratio variable scale, a value of zero represent that there is no unit or value for what is being measured, just like in the scenario above, a value of zero means such person has a neutral attitude. Mathematical relations in the form of 'ratio' can be inferred from ratio variable scales such that a person with a score of 100 means that such person has four times the score of an individual with 25. Ratio variable scales are can be employed in height, distance, weight and some other numerical measurement.
