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

The correct choice, which is the range, is not a measure of central tendency. Measures of central tendency are statistical measures that represent the center or typical value of a dataset. They provide a summary of the data with a single value indicating where most values lie.

The mean is calculated by averaging all the values; the median is the middle value when the data is ordered, and the mode is the most frequently occurring value in the dataset. All of these metrics help to understand the overall trend or central position of the data.

In contrast, the range measures the difference between the maximum and minimum values in a dataset, providing information about the spread or dispersion of the data rather than its central location. Thus, it does not qualify as a measure of central tendency, as its purpose is to indicate variability rather than an average or typical value.
