There is more to statistics than simple memorization. Learning the difference between measures such as mean and median is important, but to handle more difficult GMAT questions, you must understand what these measures represent, and how they differ.
These are the subjects of my latest video. Watch it and go beyond definitions, gaining a fuller understanding of how mean and median may be tested when you sit for the GMAT.
