Measurement of physical dimensions such as height weight distance age years of experience etc. Ratios of observations compared with reference values eg. Scales for measuring larger quantities of food like vegetables or fruit are sometimes seen in shops or at markets. Many statistical methods are appropriate only for data of certain measurement scales. The scale on the left can measure weight between text0 and text2 textkg in weight. Physical characteristics of persons and objects can be measured with ratio scales and thus height and weight are examples of ratio measurement.
A person who weights 150 pounds weights twice as much as a person who weighs only 75 pounds and half as much as a person who weighs 300 pounds. A person who is 12 metres 4 feet tall is two thirds as tall as a 18 metre 6 foot tall person. An example of the ratio level of measurement is weight. Levels and scales of measurement are corresponding ways of measuring and organizing variables when conducting statistical research. Are the examples of ratio scale. The units are divided into kilograms and grams.
We can calculate ratios like these because the scale for weight in pounds starts at zero pounds. Height relative to the mean of a reference population for a given sex and age are difficult to handle as values may fall either side of 1 100. A score of 0 means there is complete absence of height or weight.
