Mean is defined as which of the following?

• A. The most common value
• B. The middle value
• C. The average
• D. The range

Answer: (C)

Mean is the average, calculated by adding all the values and dividing by how many values there are. This makes it a measure of central tendency that represents a typical value for the data set. The other terms describe different ideas: the most common value is the mode, the middle value when the data are ordered is the median, and the range is the difference between the largest and smallest values. The mean is found by summing the values and dividing by the count (for example, with 2, 4, 6, the mean is (2+4+6)/3 = 4). Because it uses every value, the mean can be influenced by extreme numbers, unlike the median.
