- In statistics, variables are classified into different levels of measurement.
- The ratio level of measurement is the highest level and possesses a true zero point.
- A true zero point means that the value of zero on this scale represents the absence or complete absence of the attribute being measured.
- Variables at the ratio level have meaningful and interpretable ratios between values.
- In addition to having a true zero point, ratio variables allow for all mathematical operations, including addition, subtraction, multiplication, and division.
- Examples of variables that fall into the ratio level of measurement include measurements of weight, height, time, distance, and income.
- A weight of zero, for example, represents the absence of weight, and a height of zero indicates the absence of height.
- On the other hand, variables at the nominal, ordinal, and interval levels of measurement do not have a true zero point.
- These levels have varying degrees of ordering and magnitude, but they lack the attribute of a true zero.
Therefore, the most appropriate answer is option 4) Ratio.
