Which of the following is NOT a measure of central tendency?

The range is not considered a measure of central tendency because it does not summarize a set of data in a way that identifies the center or typical value of the data set. Measures of central tendency—such as the mean, median, and mode—are specifically used to represent or describe the middle point of the data.

The mean provides the average value by summing all the data points and dividing by the number of points. The median finds the middle value in a set of numbers when they are ordered, effectively highlighting the central point. The mode identifies the most frequently occurring value in the data set.

In contrast, the range only describes the spread or dispersion of the data by calculating the difference between the highest and lowest values. It does not provide any information about the central value or the typical data point within the set, which is the primary function of measures of central tendency.
