Question
Which of the following is an example of a discrete variable?
A. The temperature of a hot tub
B. The height of a horse
C. The time to complete a task
D. The number of people in an office
Answer
D. The number of people in an office
Explanation
A discrete variable can only take on specific, distinct values, typically integers or whole numbers. The number of people in an office is a count that can only be a non-negative integer, such as 0, 1, 2, etc.
The other options are examples of continuous variables:
A. The temperature of a hot tub can take on any value within a range, including fractions or decimals.
B. The height of a horse can be measured to any level of precision, resulting in values that are not necessarily whole numbers.
C. The time to complete a task can be any value within a range, including fractions of a second or minute.
