What is a variate?

In statistics, a variate is any random variable in an expression or equation.

A variate, also known as a random variable, is a way to map outcomes of random processes into quantifiable data, as in Because the study used two variates, finding conclusions was much more difficult.

Variate is also a synonym for variant, meaning someone or something that varies, as in Omicron is a variate of the virus that causes COVID-19.

Example: What is the probability (P) that the variate (X) will be less than or equal to five?

Where does variate come from?

The first records of the term variate come from around the 1810s. It ultimately comes from the Latin variāre, meaning “to vary.”

A simple variate would be quantifying the result of flipping a coin. This would be written as “X = number of heads after two coin flips.” This variate can then be inserted into various functions and math equations, often to demonstrate randomness in probability.

Variate is sometimes mistakenly used as a synonym for vary, especially on social media.
