Which of the following statements about the 'mean' is true?

It is the mode of the data set
It is the middle value when the data is ordered
It is the average of the data set
It is the largest value in the data set

The correct answer is: It is the average of the data set

The statement that the mean is the average of the data set is accurate because the mean is calculated by adding all the values in a data set together and then dividing by the number of values in that set. This process effectively provides a central value that represents the data set overall, making it a commonly used measure of central tendency in statistics. In contrast, other options describe different statistical concepts. The mode refers to the most frequently occurring value within a data set, not the mean. The middle value when the data is ordered characterizes the median, another measure of central tendency. The largest value in a data set is referred to as the maximum, not the mean. Each of these terms has its own definition, and the mean specifically relates to the average, confirming the accuracy of the chosen statement.
