A ratio scale is a quantitative measurement scale that possesses all the properties of an interval scale, but also includes a true zero point, allowing for the comparison of absolute magnitudes. This means that not only can differences between values be measured, but ratios of values are meaningful as well, making it possible to express one value as a multiple of another. This feature makes ratio scales particularly useful in various fields, including engineering and statistics, where precise measurements and comparisons are crucial.
