Detailed explanation-1: -Volume of water in a reservoir. Is the variable discrete or continuous? The variable is continuous because it is not countable.
Detailed explanation-2: -Quantitative variables may be discrete or continuous. Discrete variables can only take on a limited number of values (e.g., only whole numbers) while continuous variables can take on any value and any value between two values (e.g., out to an infinite number of decimal places).
Detailed explanation-3: -Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.
