## Continuous random variable

A random value that can take any fractional value within specified ranges, as contrasted with a discrete variable.

## Continuous Random Variable

A random variable that may take any value within a given range. That is, unlike a discrete variable, a continuous random variable is not necessarily an integer.

Roughly speaking, continuous random variables are found in studies with morphometry, whereas discrete random variables are more common in stereological studies (because they are based on the counts of points and intercepts).
