Changes

Ratio data do possess a relationship of scale, and so both have a defined zero point and cannot accommodate negative values. Many common types of measurements are on the ratio scale - including mass, length and time. Temperature is also measured on the ratio scale when measured in Kelvin rather than Celsius or Fahrenheit (note that in the case of the difference between Kelvin and Celsius, the sole difference in measurement scale relates to the position of the zero point, since both scales have the same magnitude).
