Discrete vs. Continuous Variables. Quantitative variables can be further classified as discrete or continuous. If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable; otherwise, it is called a discrete variable.
Some variables could be considered in either way. For example, a person's rating of someone else's attractiveness on a 4 point scale may be considered a continuous variable, or we may consider it a discrete variable with 4 categories. Time series data are usually collected for continuous variables, over time.
