Teenagers take to the soft drink
This is a good article to use when discussing the influence a funding body might have on the conduct of a survey. It could be used in a Media Studies course, a Health Studies course, as well as in a mathematics class. The claim of "10 times more likely" in the second paragraph can be checked later in the article. It provides good practice in writing probabilities; i.e.,
.70 = Pr(buy soft drink) = 10 x Pr(buy orange juice) = 10(.07).
The percentages of which drinks teenagers buy sum to more than 100%; students should discuss why this is so (some buy more than one type).
