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

Central tendency refers to statistical measures that summarize a dataset by identifying the central position within that dataset. The mean, median, and mode are all measures of central tendency, as they represent the center or most typical value of the data. The range, on the other hand, is a measure of dispersion, not central tendency. It calculates the difference between the maximum and minimum values in a dataset and provides information about the spread of the data, not its central value. Option A is incorrect because the mean is a measure of central tendency that calculates the average of the data. Option B is incorrect because the median is a measure of central tendency that represents the middle value of the dataset. Option C is incorrect because the mode is a measure of central tendency that identifies the most frequent value in the dataset. Option E is incorrect because, while the mean, median, and mode are measures of central tendency, the range is not.
