What is the statistical term for the value that occurs most frequently in a data set?

• A. Median
• B. Monument
• C. Memorial
• D. Mode

Answer: (D)

Mode is the value that appears most often in a data set. It shows the most common observation and is especially useful when you want to identify the frequency of a particular value, such as the most common score or category. For example, in a set like 3, 2, 3, 5, 3, 2, the mode is 3 because it occurs more times than any other value. Some data sets can have more than one mode if two or more values tie for the highest frequency, while others have no mode if every value occurs only once. The other terms describe different ideas of central tendency: the median is the middle value when the data are ordered, and the mean is the arithmetic average. The distractors are not statistics terms.
