What are the 4 types of data?
In statistics, there are four data measurement scales: nominal, ordinal, interval and ratio.
These are simply ways to sub-categorize different types of data (here’s an overview of statistical data types) ..
Is age continuous or categorical?
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.
What type of variable is height?
A variable that is “a number”. Age, height, score on an exam, response on a Likert scale on a survey are all continuous variable. It can be ordinal, interval or ratio types. Examples of continuous variables are blood pressure, height, weight, income, and age.

How do you know if a variable is discrete or continuous?
A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon.
Is gender a discrete variable?
continuous data. Discrete data: when the variable is restricted to specific defined values. For example, “male” or “female” are categorical discrete data values.
