What is the term for the most common value in a dataset?

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

Answer: (A)

The mode is the term for the most common value in a dataset because it identifies the value that appears with the highest frequency. For example, in data like 1, 2, 2, 3, 5, 2, the value 2 occurs more often than any other, so it is the mode. Note that a dataset can have more than one mode if several values tie for the highest frequency, or no mode if every value occurs only once. The mode differs from the mean (the average) and the median (the middle value), and it’s particularly useful for categorical data where you want to know the most frequent category. Range, by contrast, measures spread, not central tendency.
