Which of the following are measures of central tendency?

Measures of central tendency are statistical measures that describe the center or typical value of a dataset. The mean, median, and mode are commonly used measures of central tendency.

The mean is calculated by summing all the values in a dataset and dividing by the number of values. It represents the average of the data points. The median is the middle value when the data points are arranged in ascending or descending order, reflecting the point at which half the observations fall below and half fall above. The mode indicates the most frequently occurring value in the dataset.

Understanding these three measures provides valuable insights into the distribution of data, making them fundamental in fields such as education, psychology, and research. In contrast, other options include terms like standard deviation, variance, and range, which are measures of variability or distribution rather than central tendency. This distinction clarifies the importance of option B as the correct choice, as it exclusively lists the three recognized measures of central tendency.
