# is age nominal or ordinal

Nominal and ordinal are two different levels of data measurement. Differences Between Nominal and Ordinal Variable The ordinal variable has an intrinsic order while nominal variables do not have an order. Here’s more on Nominal, Ordinal, Interval, Ratio: The four levels of measurement in research and statistics. Interval. Nominal. On the "category axis", the scale may be nominal, ordinal, interval or ratio scale. Age as Discrete Counts. Ordinal - has an order 3. Stevens scheme has four levels: 1. For example, consider the example of age measured in days on which germinated seeds of a specific species begin to sprout leaves. Nominal scale: A scale used to label variables that have no quantitative values. There is not sensible order of these levels, that's why the variable is not ordinal. To put it in other words, ways of labeling data are known as “scales”. Nominal data involves naming or identifying data; because the word "nominal" shares a Latin root with the word "name" and has a similar sound, nominal data's function is easy to remember. The simplest measurement scale we can use to label variables is a nominal scale. Nominal - names only 2. Ordinal response variables require a model like an Ordinal Logistic Regression. 2. Age is nominal. Ratio - also has a meaningful 0. In this post, we define each measurement scale and provide examples of variables that can be used with each scale. Ratio. can be performed on ordinal variables. It is only the mode of a nominal variable that can be analyzed while analysis like the median, mode, quantile, percentile, etc. Likewise, a continuous variable may be rendered discrete because of the way people think about and measure it. 4. Nominal. 3. Ordinal data involves placing information into an order, and "ordinal" and "order" sound alike, making the function of ordinal data also easy to remember. Ordinal. *It could be argued that age isn’t on the ratio scale, as age 0 is culturally determined. For example, Chinese people also have a nominal age, which is tricky to calculate. For example, Chinese people also have a nominal age, which is tricky to calculate. So actually the variable is dichotomous, that is, nominal with two categories (levels): "yes" and "no". First, you left out “interval”. Understanding the level of measurement of your variables is a vital ability when you work in the field of data. Nominal Scale: 1 st Level of Measurement Nominal Scale, also called the categorical variable scale, is defined as a scale used for labeling variables into distinct classifications and doesn’t involve a quantitative value or order.
