15 Ratio Scale Examples

The ratio scale It is the scale that is used to measure quantitative variables and that has an absolute zero, that is, that zero implies the absence of what is being measured.

For example: The salary can be measured with the ratio scale, because it is a quantitative variable, that is, it is expressed with numbers that represent quantities and because absolute zero can be established, that is, that zero represents the absence of salary.

Scales are used in statistics (a discipline in which information about a representative sample) to measure and compare variables, which are reflected in data (the values ​​that each variable).

With the data, graphs, tables or charts are made, which allow studying, describing and classifying phenomena, objects or people, making predictions or establishing trends.

There are four scales: nominal, ordinal, interval, and ratio. They differ according to what the zero is like, according to the type of variable that they allow to analyze, according to the calculations that can be made with their values ​​and according to their properties.

Characteristics of the ratio scale

Ratio Scale Examples

1. Height. Height is measured using the ratio scale, because the values ​​of the variables are represented by positive real numbers (for example, a building can measure 30.5 meters) and can be added, subtracted, multiplied and divided and because zero indicates the absence of height. In addition, it is possible to establish the ratio and proportionality of the values ​​(for example, one building can be twice as tall as another), the identity (for example, two buildings can have the same or different height) and the magnitude (for example, the height of one building can be greater, less than or equal to the height of another) and the interval is always constant.
2. Money. The money that a person, a company or an institution has is measured with the ratio scale, because the values ​​of the variables are represented with numbers. positive reals (for example, a person may have $40,000.7) and can be added, subtracted, multiplied and divided and because zero indicates the absence of money. In addition, it is possible to carry out the operations of ratio and proportionality (for example, a company may have 40% more money than another), of identity (for example, two people can have the same amount of money) and magnitude (for example, one person can have more money than another) and the interval is always constant.

In addition, it is possible to carry out the operations of ratio and proportionality (for example, one film can last twice as long as another), of identity (for example, two films can vary in length) and magnitude (for example, the length of one film may be longer than the length of another), and the interval is always constant.
7. Mass. Mass is measured on the ratio scale, because the values ​​of the variables are represented by positive real numbers (for example, the mass of the body can be 4.5 kg) and can be added, subtracted, multiplied and divided and because zero indicates the absence of mass. In addition, it is possible to carry out the operations of ratio and proportionality (for example, the mass of one body can be twice the mass of another), of identity (for example, two objects can have different masses) and magnitude (for example, the mass of one body can be less than, greater than, or equal to the mass of another) and the interval is always constant.
8. Distance. The distance is measured with the ratio scale, because the values ​​of the variables are represented by positive real numbers (for example, the distance between two places can be 5.3 km) and they can be added, subtracted, multiplied and divided and because zero indicates the absence of distance. In addition, it is possible to carry out the operations of ratio and proportionality (for example, a distance can be half of another), of identity (for example, two distances can be equal) and of magnitude (for example, one distance can be greater than another) and the interval is always constant.
9. Height. Height is measured using the ratio scale, because the values ​​of the variables are represented by positive real numbers (for example, the height of a person can be 1.56 m) and can be added, subtracted, multiplied and divided and because zero indicates absence of height. In addition, it is possible to carry out the operations of ratio and proportionality (for example, the height of one person can be 70% of the height of another), identity (for example, example, two people can have different heights) and magnitude (for example, the height of one person can be less than the height of another) and the interval is always constant.
10. Income. The income of a person, government, company or institution is measured with the ratio scale, because the values ​​of the variables are represented by positive real numbers. (for example, the monthly income of a government can be $567,398,097.37) and can be added, subtracted, multiplied and divided and because zero indicates no income.
