Which term is commonly used to denote the arithmetic average of a dataset?

• A. Mean
• B. Acquisition
• C. Appraise
• D. Specifically

Answer: (A)

The term used for the arithmetic average is the mean. You find it by adding up all the numbers in the dataset and then dividing that total by how many numbers there are. The mean serves as a central value that represents the dataset, giving a sense of the typical size around which the data cluster. The other words don’t relate to this mathematical idea: acquisition means obtaining something, appraise means to assess value, and specifically means precisely or in detail. In everyday language, people say “average,” but the precise statistical term for the arithmetic average is the mean.
