What is the term for the average value of a set of numbers?

The average value of a set of numbers is referred to as the mean. The mean is calculated by summing all the values in the dataset and then dividing that sum by the number of values. This measure provides a central value around which the other numbers are distributed and is commonly used in statistical analysis to understand data trends.

To clarify the context of the other terms: the mode represents the number that appears most frequently in a dataset, while the median is the middle value when the numbers are arranged in ascending order. The range, on the other hand, measures the difference between the highest and lowest values in the set. Each of these represents different aspects of a dataset, but when specifically addressing the average or central tendency, the mean is the appropriate term.
