Algebra-1

The option that represents a discrete variable is the number of students in a classroom.

This is discrete data because it consists of countable whole numbers (0, 1, 2, etc.). We cannot have a fraction of a student.

The other options are incorrect because:

Option A: Height of a person

This is a continuous variable, as height can take any value within a range and can include fractions or decimals (e.g., 5.5 feet).
