Unfortunately, the answer has nothing to do
with science and everything to do with
advertising. When you read or hear an
advertiser's claim, you have to carefully listen
to the small print. Revlon claims that their
lipstick lasts 'up to 12 hours'. That could mean
just about anything. It could mean that they did a
survey and all the women reported their lipstick
lasted 12 hours or it could mean that 99% of the
women reported their lipstick's lasted only 1 hour
and only one woman reported it lasted 12 hours.
(Maybe she was sleeping the whole time!)
you start looking at advertisements critically in
this manner you will discover that many
manipulate data to make their products look good.
Learning how to examine data and information
critically in this manner will help you to become
not only a smart consumer but a good scientist!
