What term describes the number that appears most frequently in a series of numbers?

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

Answer: (C)

The term that describes the number that appears most frequently in a series of numbers is the mode. In a dataset, the mode is the value that occurs with the highest frequency. For example, in the sequence of numbers {1, 2, 2, 3, 4}, the number 2 is the mode because it appears more often than any other number in the set.

Understanding the mode is essential since it provides insight into the most common value within a dataset, which can be particularly useful in fields like statistics and data analysis. Other measures such as median, mean, and range serve different purposes. The median is the middle value when the numbers are arranged in order, while the mean is the average of the numbers. The range measures the difference between the highest and lowest values in the dataset. Each of these terms offers unique information, but the mode specifically identifies the most frequently occurring number.
