advantages and disadvantages of measures of central tendency

The median is less affected by outliers and skewed data. If there are extreme values (e.g. The extent to which the observations in a sample or in a population vary about their mean is known as dispersion. Defined as the difference between the largest and smallest sample values. What are the three types of averages that can be used to describe a set of scores? Therefore, it is not an appropriate measure of central tendency for skewed distribution. A conceptual understanding of measures of central tendency is basic to understand many aspects of educational measurement and thus essential for inclusion in this resource book.
