Given the data set: Which value is the mode?

• A. 35
• B. 37
• C. 41
• D. 43

Answer: (C)

The mode is the value that appears most often in a data set. To find it, you count how many times each value occurs and identify the one with the highest frequency. In this data set, 41 shows up more times than any other value, so it is the mode. The other values—35, 37, and 43—occur less frequently, so they are not the mode. Remember, a data set can have multiple modes if two values tie for the highest frequency, or no mode if all values occur equally often.
