Final answer:
During a fire drill, the teacher counts students which represent quantitative discrete data since the students are counted in whole numbers.
Step-by-step explanation:
During a fire drill, a teacher counts the number of students standing outside away from the building. The type of data this represents is quantitative discrete data. Quantitative discrete data are numerical and can only take on certain values. They are the result of counting things where the values cannot be fractional or decimal. In the context of the fire drill, students are being counted in whole numbers (1, 2, 3, etc.), and you cannot have a fraction of a student. Therefore, each student represents one whole unit, and this is an example of quantitative discrete data. Other similar examples include the number of phone calls received per day or the number of tickets sold to a concert.
