asked in category: General Last Updated: 23rd March, 2020# What type of level of measurement is age?

**Age**is, technically, continuous and ratio. A person's

**age**does, after all, have a meaningful zero point (birth) and is continuous if you

**measure**it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.

Keeping this in view, is age nominal or ordinal?

There is no order associated with values on **nominal** variables. [Ratio] **Age** is at the ratio level of measurement because it has an absolute zero value and the difference between values is meaningful. For example, a person who is 20 years old has lived (since birth) half as long as a person who is 40 years old.

Additionally, is age an ordinal variable? To remember this **variable** type, think **ordinal** = order. For example, an **age variable** measured continuously could have a value of 23.487 years old—if you wanted to get that specific! A continuous **variable** is considered ratio if it has a meaningful zero point (i.e., as in **age** or distance).

Keeping this in view, what type of measurement scale is age?

ratio scale

Is year a ratio or interval?

**Interval** and **ratio** are the two highest levels of measurement in Stevens' original system. Unlike nominal- and ordinal-level data, which are qualitative in nature, **interval**- and **ratio**-level data are quantitative. Examples of **interval** level data include temperature and **year**.
