The arithmetic average of a distribution is called what?

• A. Mean
• B. Average
• C. Median
• D. Mode

Answer: (A)

The arithmetic average is the mean. It’s calculated by adding all the values in a distribution and dividing by how many values there are, giving a single representative value that summarizes the data’s central point. In statistics, mean is the precise term for this calculation, while the word “average” is a general, everyday synonym that’s often used interchangeably but isn’t the formal name. The other terms describe different measures of central tendency: the median is the middle value when the data are ordered, and the mode is the most frequent value. So the correct term for the arithmetic average is mean.
