Award winning mathematics teacher Dr Murray Siegel helps those who struggle to understand mathematics, teaching not only the practical methods used in mathematics but the theory behind why these methods work. This lesson teaches you how to find the mean of a set of numbers; to find the median of a set of numbers; why the median is a better measure of tendency when the data contain extreme values; and to compute the range of a set of data.
