A continuous variable is a specific kind a quantitative variable used in statistics to describe data that is measurable in some way. If your data deals with measuring a height, weight, or time, then you have a continuous variable. Let's further define a couple of the terms used in our definition. A variable in statistics is not quite the same as a variable in algebra. In statistics, a variable is something that gives us data.
Discrete vs. Continuous. 1  A discrete variable is one with a well defined finite set of possible values, called states. Examples are: the number of dimes in a purse, a statement which is either âtrueâ or âfalseâ, which party will win the election, the country of origin, voltage output of a digital device, and the place a roulette wheel stops.
