In statistical terms, the average of a set of numbers is also known as what?

The average of a set of numbers in statistical terms is referred to as the mean. The mean is calculated by adding all the numbers together and then dividing by the total count of those numbers. This concept is fundamental in statistics as it provides a measure of central tendency, indicating where the center of a data set lies.

In contrast, the median refers to the middle value in a list of numbers when they are arranged in order, which may differ from the mean, especially in datasets with outliers. The term ratio represents a quantitative relationship between two numbers, often expressed as a fraction, but it does not serve as a measure of average. Standard score, or z-score, indicates how many standard deviations a data point is from the mean, but it is not synonymous with the average itself. Thus, mean is the correct term to represent the average in a statistical context.
