In statistics, mean refers to what?

• A. The arithmetic average of a set of numbers.
• B. The middle value.
• C. The most frequent value.
• D. The sum of values.

Answer: (A)

Mean is the arithmetic average, a measure of central tendency that represents the typical value of a data set. It’s found by adding all the numbers together and dividing by how many numbers there are. This definition directly matches the idea of an average that summarizes the data with a single representative value. For example, with values 2, 4, and 6, the mean is (2 + 4 + 6) ÷ 3 = 4. This differs from the middle value (the median) and the most frequent value (the mode), and it isn’t just the total sum of the values.
