Quizplus · Accepted Answer

Continuous random variables can take on any value within a range. I (weight of an elephant), II (time to answer a questionnaire), and IV (square feet of countertop in a kitchen) can all vary continuously. III (number of floors in a skyscraper) is discrete because it can only take on integer values.
