    Explanation
    The range is not a measure of central tendency because it measures the dispersion or spread of the data, rather than summarizing the central or typical value. The range is calculated by subtracting the minimum value from the maximum value in a dataset, providing information about the overall variability of the data points. Measures of central tendency, on the other hand, provide a single value that represents the center or average of the data, such as the mean, median, or mode.
