Each day people are inundated with statistical information from advertisements ("4 out of 5 dentists recommend"), news reports ("polls show the incumbent leading by four points"), and even general conversation ("half the time I don't know what you're talking about"). Experts and advocates often use numerical claims to bolster their arguments, and statistical literacy is a necessary skill to help one decide what experts mean and which advocates to believe. This is important because statistics can be made to produce lies and misrepresentations of data that may seem valid.

The Alexa Internet web traffic reports, for example, are known to be biased for several reasons, one of which is that their toolbar only works with the Internet Explorer browser [1]. The wording of a poll question may introduce a bias, and thus can even be used intentionally to produce a biased result. Good polls use large samples and unbiased techniques, with much time and effort being spent in the design of the questions and polling strategy.
