Which of the following is a measure of central tendency?

The median is a measure of central tendency because it represents the middle value in a data set when the values are arranged in ascending or descending order. The median effectively summarizes the data set by providing a single value that reflects the center point, thereby indicating where most of the data points lie. It is particularly useful when dealing with skewed distributions, as it is not affected by extreme values as means can be.

In contrast, standard deviation and variance are measures of dispersion, indicating how spread out the values in a data set are rather than where they center around. The range, which is the difference between the highest and lowest values in a data set, also reflects dispersion rather than central tendency.
