What is a discrete random variable?

Back

A discrete random variable is a variable that can take on a countable number of distinct values, often representing counts or whole numbers.

What is a continuous random variable?

Back

A continuous random variable is a variable that can take on an infinite number of values within a given range, often representing measurements.
