What is the most frequently occurring value(s) in a distribution?

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

Answer: (A)

The mode is the value that appears most often in a data set, so it identifies the most common observation in a distribution. This makes it the best answer when the question asks for the most frequently occurring value. Unlike the mean (the average of all values) and the median (the middle value), the mode specifically reflects frequency, not overall balance or midpoint. The range describes how spread out the data are, not which value is most common. For example, in the set 1, 2, 2, 3, 4, the value 2 is the mode because it occurs twice, more than any other value; the mean is 2.4 and the median is 2. If every value occurred with the same frequency, there would be no single mode.
