Calculating The Mean (Average) (SAT)

This video starts with how to find the average of a group of numbers, but then it gets into trickier word problems using the average formula. Also covered are SAT-style average word problems where they ask you to solve for a missing number based on the average of the rest of the group, or where you're supposed to say what the biggest member of a set could be based on the average of all the numbers.
