Which statistic is defined as the average value obtained by adding all values and dividing by the count?

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

Answer: (A)

The mean is defined as the average value obtained by adding all the values and dividing by how many values there are. For example, with data 2, 4, 6, the mean is (2 + 4 + 6) / 3 = 4. The mean represents the balance point of the data and summarizes the overall level. This fits the description precisely, whereas the median is the middle value when data are ordered, the mode is the most frequent value, and the range is the difference between the largest and smallest values.
