Subscribe:    / @manhattanprepgmat6791   In this session, GMAT instructor Reed Arnold guides you through GMAT content and strategy. Many GMAT questions ask you to consider sets of numbers based on the values we used to describe those sets--mostly, averages and medians. In this lesson, Reed guides you through problems about these topics and introduces a more intuitive approach to averages--focusing on their role as the 'balance point' of the set--to avoid mindless calculation based on the average formula. 0:00 Intro and Question Set 1 11:30 The Average is the Balance Point 26:05 Balances, Medians, Extremes, and Set Building 41:40 Question Set 2 47:50 Visualizing Large Sets, Medians and Percentiles 52:49 Set Building when values must be unique 58:43 Question Set 3 1:06:45 Symmetrical, perfectly balanced sets and medians/averages 1:15:05 Range vs. Number of Numbers 1:18:53 More set building 1:21:09 Sets with different possible Medians 1:30:50 Takeaways Want to tune in live to learn with a Manhattan Prep GMAT instructor in real time?
