More than eight times as many, in fact.<br /><br />"Median" means the figure you find at the exact middle when you line up all the prices in rank order -- so here, it would be the 50th (or, actually, the 50-and-a-halfth) price in the list of 100.<br /><br />In the Top 100 there are 48 comics at $2.99, 1 comic book at $3.50, 45 comics at $3.99, and 6 at $4.99. So the most common price is $2.99 and the exact middle of the line of 100 prices is $3.99. <br /><br />Put another way, anked in ascending order of price, comics #1-48 are $2.99, comic #49 is $3.50, comics #50-94 are $3.99, and comics #95-100 are $3.99. We thus see that had there been one more $2.99 book, the median would have been $3.50 -- and had there been two more, the median would have been $2.99.<br /><br />That's why the median is sometimes misleading, since it shields the large gaps between prices; the other 48 books could have been at $0.01, and the median would still be $3.99. But it is useful to look at sometimes: if we see that the number is far out of synch with the average, it means that there are outlier books at either end distorting the average.John Jackson Millerhttp://www.blogger.com/profile/02450012837939955658noreply@blogger.comtag:blogger.com,1999:blog-1817961213743889523.post-3547826876250153842010-07-10T01:59:40.127-05:002010-07-10T01:59:40.127-05:00If my memory of the meaning of "Median" ...If my memory of the meaning of "Median" is correct, then does that mean this month is the first month where there have been more comics costing more than $3.99 or more than less than 3.99?Paul Nolanhttp://www.blogger.com/profile/08313427362919606266noreply@blogger.com
