Mean is defined as which of the following?

Mean is defined as which of the following?

• A. The range of values
• B. The median
• C. The mode
• D. The average of all data points

Answer: (D)

Mean is the average value of a data set. It’s found by adding all the data points together and dividing by how many data points there are. This uses every value in the set, so each data point contributes to the final result, and extreme values can pull the mean toward them. For example, with data 1, 2, 3, 4, the mean is (1+2+3+4)/4 = 2.5. This definition matches the choice that describes the average of all data points. The other terms refer to different ideas: the range is the difference between the largest and smallest values, the median is the middle value when the data are ordered, and the mode is the most frequent value.
