What characteristic defines discrete data?

Discrete data is defined by its ability to take on only specific, distinct values. This means that discrete data can be counted and represented as whole numbers, such as the number of students in a classroom or the number of cars in a parking lot. Unlike continuous data, which can take on any value within a given range (such as heights or temperatures), discrete data is limited to particular values within an interval.

The characteristic of taking only certain exact values allows for clearer organization and analysis, making it suitable for many statistical and mathematical applications. Hence, the foundation of discrete data lies in its distinctiveness and countability, differentiating it from other types of data which might be represented in varying forms like percentages or broader observational categories.
