What term describes the average of a series of numbers calculated by adding them and dividing by the count?

• A. Mean
• B. Median
• C. Mediation
• D. Merger

Answer: (A)

The mean is the average of a group of numbers, found by adding all the values together and then dividing by how many values there are. This arithmetic average provides a single representative value that reflects the overall level of the data, because every number contributes to the total. It differs from the median, which is the middle value in an ordered list and can give a different sense of the center if the data are skewed. The other terms don’t describe this concept: mediation refers to resolving disputes, and merger means combining entities in business.
