Which measure is defined as the most frequently occurring item?

• A. The maximum value
• B. The most frequently occurring item
• C. The middle value
• D. The sum of all values

Answer: (B)

The main idea is to identify the value that appears most often in a data set. This is called the mode—the item with the highest frequency. It directly matches the phrase “the most frequently occurring item,” so it’s the best fit. The maximum value is just the largest number in the set, not necessarily the one that occurs most often. The middle value refers to the median, the point that separates the higher half from the lower half. The sum adds up all the values, which is a total, not a measure of frequency. Keep in mind that a data set can have more than one mode if several values occur with the same highest frequency, and in some cases there may be no mode if all values occur equally often.
