Quizplus · Accepted Answer

The mean is the average of a data set, calculated by adding up all the values and dividing by the total number of values. It represents the central location of the data set. A is incorrect because the measure of spread is typically represented by measures like variance or standard deviation. B is incorrect because the middle value in a sorted set of data is called the median, not the mean. D is incorrect because the observation with the highest frequency is the mode, not the mean.
