What is the key difference between a discrete and a continuous random variable?
- Discrete variables are predictable, continuous variables are not
- Discrete variables can only take on a countable number of values, continuous variables can take on any value within a certain range
- Discrete variables can take on any value, continuous variables can take on only integer values
- There's no difference between discrete and continuous random variables
Discrete random variables are variables that can only take on a countable number of values, such as integers, while continuous random variables can take on any value within a certain range or interval.
