When scores in a distribution are averaged, the statistic is called?

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

Answer: (A)

The mean is the statistic you get when you average scores. It’s the arithmetic average, calculated by adding all the scores together and dividing by how many scores there are. For example, scores 2, 3, 7, and 9 sum to 21, and the mean is 21 ÷ 4 = 5.25. The mean represents a central value around which the data cluster, assuming each score contributes equally. Other terms describe different ideas: the median is the middle value when the data are ordered; the mode is the most frequently occurring value; the range is the difference between the highest and lowest scores. The mean is the standard way to summarize the overall level when the distribution isn’t heavily skewed and there aren’t extreme outliers.
