Range, variance and standard deviation as measures of dispersion
By Khan Academy
This video goes over the main ways we measure dispersion of data, then shows those vlaues for two different data sets. Remember that simply comparing the means or medians of two data sets is not sufficient to fully compare the data. Understanding how data is arranged about the "center" of the data is also critical in understand and comparing the sets
