The average of a set of numbers is referred to as the mean. The mean is calculated by summing all the numbers in the set and then dividing that sum by the total number of elements in the set. This calculation provides a central value that represents the data, which is especially useful for understanding the overall performance or tendency within a dataset.

In contrast, the median represents the middle value when the numbers are arranged in ascending or descending order, providing insight into the distribution of the data without being affected by extreme values. The mode is the number that appears most frequently in a set, which highlights the most common value rather than the overall average. The range measures the difference between the largest and the smallest number in the set, indicating the spread or variability of the data but not providing a measure of central tendency like the mean does. Thus, mean is indeed the term used to identify the average of a set of numbers.
