What is a characteristic of a continuous random variable?

• A. It is always non-negative
• B. It has a finite number of outcomes
• C. There’s no natural finite set to list all possible outcomes
• D. It can only take integer values

Answer: (C)

A continuous random variable is defined by its ability to take on an infinite number of possible values within a given range. This characteristic arises from the nature of continuous data, which can include measurements such as height, temperature, or time. Since the values are not restricted to whole numbers, you cannot enumerate or list all possible outcomes as you would with a discrete random variable. Instead, continuous random variables can take any value within an interval, making it impossible to create a complete finite list of all possible outcomes. The other choices present traits that do not accurately describe continuous random variables. Continuous random variables are not necessarily non-negative, nor do they have a finite number of outcomes or limit themselves to integer values. They can indeed take negative values, encompass an infinite range of outcomes, and include both integer and non-integer values, highlighting the distinct difference between continuous and discrete variables.
