In an article titled “Technology Workers Are Young (Really Young),” the New York Times reported median ages for a number of companies (Hardy, 2013). The reporter wrote: “The seven companies with the youngest workers, ranked from youngest to highest in median age, were Epic Games (26); Facebook (28); Zynga (28); Google (29); and AOL, Blizzard Entertainment, InfoSys, and Monster.com (all 30). According to the Bureau of Labor Statistics, only shoe stores and restaurants have workers with a median age less than 30.” 

a. Explain why the reporter provided medians rather than means for employee ages. 

b. Why might it be easier to use medians rather than means to compare ages across companies?
