What is the average of a set of values calculated by summing and dividing by the count?

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

Answer: (A)

The average calculated by summing all the values and dividing by how many there are is the arithmetic mean. It represents a balance point of the data, giving each value an equal influence in the overall average. For example, if you have values 2, 4, and 8, you add them to get 14 and divide by 3, yielding an average of about 4.67. This differs from the median (the middle value when the data are ordered), the mode (the most frequent value), and the range (the difference between the largest and smallest values). The mean is a useful measure for numerical data, but it can be affected by outliers, since extreme values can pull the average away from most data points.
