Quizplus · Accepted Answer

The possible responses to the question "What do you think is the current number of people unemployed in the country?" are values from a discrete numerical random variable. This is because the number of people unemployed is a countable quantity and can only take on certain specific values (e.g. 5 million, 10 million, 15 million), rather than a continuous range of values.
