What is a key difference between discrete and continuous random variables?
What is a key difference between discrete and continuous random variables?
- Discrete random variables have unbounded outcomes, while continuous have countable outcomes.
- Discrete random variables can be measured, while continuous variables can only be counted.
- Discrete random variables can only assume values from specific intervals, unlike continuous variables.
- Discrete random variables rely on finite sample spaces, whereas continuous variables operate on infinite ranges. (correct)
