What is an example of ratio level measurement?

One of the most common examples of a ratio scale is the Kelvin scale. A Kelvin scale possesses the true zero point. This means that, while 40 degrees is not twice hot as 20 degrees on a Celsius or Fahrenheit scale. In a Kelvin scale, 40K is twice as hot as 20K because of the presence of true zero.

Why is ratio the highest level of measurement?

The fourth and highest level of measurement is the ratio level. Data at the ratio level possess all of the features of the interval level, in addition to a zero value. … So ratios can be formed between the data. At the ratio level of measurement, not only can sums and differences be calculated, but also ratios.
