Question

Which of following examples represents a discrete data constraint with viable solutions?

A. Average score on a test
B. Average weight of all the newborns in a hospital ward
C. Distance between points
D. Number of tests passed

Answer 1

The example that represents a discrete data constraint with viable solutions is:

**D. Number of tests passed**

This is because the number of tests passed can only take on whole number values (e.g., 0, 1, 2, 3, etc.), making it a discrete variable.

In contrast:
- A. Average score on a test represents continuous data because it can take on any value within a range.
- B. Average weight of newborns is also continuous data, as weight can vary and take on fractional values.
- C. Distance between points is typically measured in continuous units (like meters), which also allows for an infinite number of decimal places.

Thus, D is the best choice for discrete data.
