The average of a data set is called the what?

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

Answer: (C)

The mean is the average value of a data set. You find it by adding all the numbers together and dividing by how many numbers there are. This measure uses every value in the data, so unusually large or small numbers can pull the result toward them. It’s a common way to summarize the overall level of a data set. In contrast, the median is the middle value when the data are arranged in order, the mode is the most frequent value, and the range is the difference between the largest and smallest values.
