But Lies, Damned Lies, and Statistics TVTropes entry contains dosens of relevant examples of how statistics can be used to lie. Just for a couple of them:

•Newspapers love doing this with drug related stories. It's almost impossible to see Ecstasy mentioned in a British newspaper without the qualifier "That killer drug", the supporting statistic is of course that a dozen people die per year from consuming it. Yet over the course of a year they will rack up an impressive body count in stories about fatal car accidents without ever devolving into calling cars "Those murderous rampaging kill bots" How many Britons drive? How many take E?
â—¦A related strategy was used by US president Richard Nixon to portray marijuana as a gateway drug. His anti-drug team estimated that 80% of marijuana users go on to use cocaine, a figure which they obtained by taking the number of cocaine users and dividing it by the number of those users who had started by using marijuana. This ignored the fact that out of all marijuana users, only about one in 2,400 go on to use cocaine. And related to that, most people willing to take a drug as dangerous as cocaine are willing to take a drug as relatively safe as marijuana. It's the same reason most marijuana smokers have drunk alcohol at some point, and why most alcohol drinkers have drunk something with caffeine in it. Water: the Gateway Chemical

And similarily, there are just as many examples that can be made by replacing the actual cause with a fictional one, like I once heard about a survey:

Consuming vitamins leads to a shorter life span

That one failed to put into account that it's sickly and unhealthy people that tend to consume vitamins, and they have shorter life span from that and not from vitamin consumption.
