Which term describes the central tendency defined as the mean of values?

• A. Percent
• B. Axis labels
• C. Median
• D. Mean

Answer: (D)

Mean is the arithmetic average, a way to describe the center of a data set by treating every value equally. You find it by adding all the numbers together and dividing by how many numbers there are. This single value reflects the overall level of the data because it incorporates every data point. For example, with values 2, 4, and 6, the mean is (2 + 4 + 6) ÷ 3 = 4. The mean uses every value, so it’s sensitive to very large or very small outliers, which can pull it away from other measures of center like the middle value (the median) or the most frequent value (the mode). In contexts where data are reasonably balanced and you want a single representative value that participates in further calculations, the mean is the standard descriptor of central tendency.
