The difference between the highest and lowest values in a set.

The difference between the highest and lowest values in a set.

• A. Average
• B. Quotient
• C. Equivalent
• D. Range

Answer: (D)

This question tests understanding of describing how spread out the numbers are in a data set. The range is the spread between the largest and smallest values, found by subtracting the smallest value from the largest one. It directly matches the phrase “difference between the highest and lowest values.” For example, in a set like 3, 8, 2, and 10, the highest is 10 and the lowest is 2, so the range is 8. The other terms don’t describe this kind of spread: the average is a measure of central tendency, the quotient is the result of division, and equivalent means equal in value. So the range is the correct concept.
