How can a discrete random variable be distinguished from a continuous random variable?
How can a discrete random variable be distinguished from a continuous random variable?
- Discrete variables are measured on a continuous scale, while continuous variables are measured on a discrete scale.
- Discrete variables are always quantitative, while continuous variables can be either quantitative or qualitative.
