In a set of numbers, what is the term for the middle value when arranged in order?

The middle value in a set of numbers, when they are arranged in ascending or descending order, is referred to as the median. To determine the median, you would first organize the numbers from the smallest to the largest. If the set has an odd number of values, the median is the number that lies exactly in the center. If the set has an even number of values, the median is calculated by finding the average of the two middle numbers. This measure is particularly useful in statistics because it provides a better representation of the dataset in the presence of outliers, unlike the mean, which can be heavily influenced by extremely high or low values.

The mean is the average of the numbers, the mode is the number that appears most frequently, and the range represents the difference between the highest and lowest values in the set. Each of these terms has a distinct definition, but when specifically looking for the middle value, median is the correct term to apply.
