Which statistical term represents the sum of a set of numbers divided by the count of numbers?

The term that represents the sum of a set of numbers divided by the count of numbers is the mean. The mean is a measure of central tendency and is calculated by first adding all the values in the data set to find their total, and then dividing that total by the number of values in that set.

This process provides a single value that summarizes the overall data set, giving an idea of the "average" value. For example, if you have a set of test scores: 80, 85, and 90, you would add these together to get 255, and then divide by 3 (the number of scores), resulting in a mean of 85. This illustrates how the mean reflects the balance point of the data and is widely used in statistics to provide insight into various data sets.
