You are part of a school and have to report the results of standardized test scores. Which measure of central tendency would you use? Assume that you don\'t know how your students will perform; so consider the general effects of outliers on the three measures of central tendency. Research and summarize the general effects that outliers have on each of the measures of central tendency. Then, using some real values, provide an example of how the three measures of central tendency vary due to outlier effects.

Solution

There are three measures of central tendency- mean, median, mode. Among these three mesaures median is the best to  report the results of standardized test scores because mean is affected by the outliers. But, median is not affected by the outliers. Hence median is recommended.
