Which example represents discrete data?

Explanation:
Discrete data are counts of separate events and take only whole-number values. The number of visits to a PT clinic fits this, because you count each visit as one unit and you can’t have a fraction of a visit. Other options are continuous data: ROM measured in degrees can vary smoothly across a range and include fractional values; distance in meters and time in seconds can be measured to any precision and also yield non-integer values. Recognizing this distinction helps decide how to summarize data and which statistical approaches are appropriate.
