When there is an EVEN number of terms, then the MEDIAN is the AVERAGE of the two 'middle terms.' Here, we have 6 numbers: 8, 12, 32, 40, 48, 63 The MEDIAN of this group is the average of 32 and 40... 72/2 = 36. Final Answer: D GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 Quote: During the course of an hour, an employee at Ultimate Packing Solutions, wrapped packages weighing 48, 32, 63, 12, 40 and 8 pounds.

I have many difficulties to understand why that is the correct answer. Thanks. Hi Swerve, Let's take a look at your question. We are asked to find the median weight of the packages weighing 48, 32, 63, 12, 40, 8. To find median of ungrouped data, we arrange the data in ascending or descending order. The weights in ascending order can be written as: $$8,\ 12,\ 32,\ 40,\ 48,\ 63$$ When the number of values is odd, the median is equal to the middle value of the data arranged in ascending or descending order but When the number of values is even the median is the average of the two middle values of the data arranged in ascending or descending order. In this data, we can see that we have six values. The middle two values are 32 and 40. Therefore, $$Median\ =\ \frac{32+40}{2}$$ $$Median\ =\ \frac{72}{2}=36$$ Therefore, Option D is correct. Hope it helps. I am available if you'd like any help. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee. Our average student improves 98 points.
