What statistical term describes the average of a set of data?

• A. Population
• B. Variance
• C. Median
• D. Mean

Answer: (D)

The average of a set of data is referred to as the mean. It is calculated by summing all the individual data values and then dividing this total by the number of data points. The mean provides a measure of central tendency, representing a typical value in the dataset. It is particularly useful in summarizing the data and making comparisons. In contrast, the other terms refer to different concepts. For instance, population pertains to the entire group of individuals or items that you want to analyze, while variance is a measure that quantifies the spread or dispersion of the data points from the mean. The median, another measure of central tendency, represents the middle value of a data set when organized in ascending or descending order. However, none of these terms describe the average itself, which is why the mean is the appropriate choice in this context.
