What does the median represent in a set of numbers?

• A. The lowest number
• B. The average of all numbers
• C. The middle number when ordered
• D. The number that occurs most frequently

Answer: (C)

The median represents the middle number in a set of numbers when they are arranged in order from least to greatest. To find the median, you first organize the data points in ascending order. If there is an odd number of values in the list, the median is the value exactly in the middle. If there is an even number of values, the median is calculated by taking the average of the two middle numbers. This characteristic of the median makes it an effective measure of central tendency, especially in datasets that may contain outliers, as it provides a better representation of the typical value than the mean in such cases. The other options describe different statistical measures: the lowest number refers to the minimum, the average represents the mean, and the number that occurs most frequently describes the mode. These concepts, while important, do not define the median. The clarity of the median as a measure helps in understanding its unique role in analyzing data.
