What is the mean?

What is the mean?

• A. The average value of a set of numbers.
• B. The median value of a set.
• C. The mode value of a set.
• D. The sum of all values.

Answer: (A)

Mean is the average value of a set of numbers. You find it by adding all the numbers together and then dividing by how many numbers there are. For example, with 2, 4, and 6, the mean is (2 + 4 + 6) / 3 = 4. This gives a single value that represents the central tendency of the data. The median is the middle value when the data are ordered, the mode is the value that occurs most often, and the sum is just all the values added up without averaging. The mean incorporates every data point, which is why it reflects the overall level of the dataset.
