25). Thus, Time, measured from the “Big Bang”, is on a

ratio scale

, and so is Length when measured from the location of that same event. Length, in yards or meters, and Time, in days or years, are on interval scales.

Is age an interval or ratio?

A

ratio

scale has the first characteristic of the interval scale (interval) but also has a meaningful zero point—which means the absence of the attribute. This enables multiplication and division on the values. Using the aforementioned definition, age is in a ratio scale.

What are the characteristics of interval scale?

Interval Scale: Definition. The interval scale is a quantitative measurement scale where

there is order, the difference between the two variables is meaningful and equal, and the presence of zero is arbitrary

. It measures variables that exist along a common scale at equal intervals.

What is the difference between an interval and a ratio scale?

In an interval scale, the

data collected can be added, subtracted, and multiplied

. The scale allows computing the degree of difference but not the ratio between them. A ratio scale permits not only addition, subtraction, and multiplication but also division. That is, you can calculate the ratio of the values.
