lot of money. “That’s what makes
these such risky endeavors,” says
Bock. If a movie bombs at the box
office, a sequel may not even get
made. When last year’s The Mortal
Instruments: City of Bones flopped,
production on the sequel halted.
Bock says one reason many
adaptations flop is that the studios
rush to release them, not taking
care to make sure that the script,
the cast, the director, and the
look of the film match viewers’
expectations. Other factors can
also contribute to a flop, like
a star’s off-screen scandals or
plain old bad acting.
Divergent, however, seems
to be on track to be the next
big thing. Based on the book by
Veronica Roth, it’s set in a future
in which society is divided into
four factions based on people’s
personalities. Lionsgate, the
studio that’s producing the film,
made faithful movie adaptations
of the Hunger Games series,
which is a good sign, says Bock.

Harry Potter, Bella Swan,
and Katniss Everdeen
are all book characters
whose stories have made it big
on the big screen. Last year, eight
movie adaptations of young-adult
books were released—the most of
any year. However, only The Hunger
Games: Catching Fire was a hit.
That’s not stopping studios from
continuing to make these movies.
Five more are scheduled for release
this year, including Divergent, which
comes out this month.
Movies based on young-adult
novels date back to 1939’s A Little
Princess, which is based on the
novel by Frances Hodgson Burnett.
But they weren’t always the
blockbusters they often are now. “It
all started with Harry Potter,” says
Jeff Bock, an analyst for Exhibitor
Relations, a company that provides
box-office statistics. “The movies
were received with just as much
passion as the books, with lines
around the corner.” However, only
the Twilight and Hunger Games
films have come close to that kind
of success, says Bock.
When a movie studio buys the
rights to a young-adult novel today,
it usually means buying the rights
to an entire series, which takes a

Measures of central tendency
(mean, median, and mode)
are used to analyze a data
set. Sometimes choosing just
one to support a claim can be
misleading, especially if there
are outliers. An outlier is a data
value that’s either much greater
or much less than the median.
Young-adult book adaptations
are often either hits or flops.
These extremes are often
outliers that can skew data
when describing the success of
a year’s films.
EXAMPLE: What is the best
measure of central tendency to
analyze domestic gross earnings
of the young-adult adaptations
from 2004 below?
● Ella Enchanted: $23 million
● The Princess Diaries 2:
Royal Engagement:
$95 million
● Lemony Snicket’s A Series of
Unfortunate Events:
$119 million
● Harry Potter and the Prisoner
of Azkaban: $250 million
The median is $107 million.
The mean is $121.8 million.
There is no mode.
Here, the mean is misleading
because the Harry Potter film’s
high gross raised the mean.
The other movies made much
less than the mean. The median
is closer to the grosses of the
bulk of the films and is the best
measure of central tendency.
