In a data set, which value repeats most often?

• A. Mean
• B. Range
• C. Mode
• D. Median

Answer: (C)

The value that repeats most often is the mode. It identifies the most common observation in a data set—the number (or item) that appears with the highest frequency. For example, in a list like 2, 8, 3, 8, 5, 8, 1, the number 8 shows up more times than any other value, so it is the mode. While the mean is the average, the median is the middle value when ordered, and the range measures spread (max minus min), none of those focuses on how often a value occurs. Some data sets can have more than one mode if multiple values share the highest frequency, making the data multimodal.
