When is the mean the best measure of central tendency? When is the median the best measure of central tendency?

Mean = sum of all the values of observations in a data set ÷ number of observations

If the values of all the observations in a data set are ordered (ascending or descending), the median value is the middle value (i.e., 50% of the values are below the median and 50% of the values are above the median). Mean is affected by extreme values.

Mean can be calculated only for the quantitative ...
