Misleading Statistics Examples in Advertising and The News

Statistics Blog > Misleading Statistics Examples

In my previous post, I wrote about misleading graphs in real-life. Misleading statistics examples ranged from Fox News’ coverage of politics to The Times newspaper’s claim that it beat the competition with slightly distorted graphs about circulation. Graphs aren’t the only way to distort statistics. In fact, stats are very easy to distort because most people don’t understand stats — even “experts!” See Even Physicians Don’t Understand Statistics for a run-down on how doctors frequently misread stats about your odds of cancer. Misleading statistics examples are abundant in advertising and in the news. Here are some of the most famous misleading statistics examples…and the most distorted.

Misleading Statistics Examples in Advertising.

80% of dentists will recommend everything.

Anyone remember Colgate’s claim that 80% of dentists recommended the brand? You won’t be seeing that slogan again, at least not in the UK. Consumers were led to believe that 80% of dentists recommended Colgate while 20% recommended other brands. It turns out that when dentists were surveyed, they could choose several brands — not just one. So other brands could be just as popular as Colgate. This completely misleading statistic was banned by the Advertising Standards Authority.

If it sounds to good to be true…

reebokIn 2009 and 2010, Reebok made the following claims about its EasyTone and RunTone shoes: Lab tests “proved” that the shoes work “your hamstrings and calves up to 11% harder and tone your butt up to 28% more than regular sneakers … just by walking!”. The figures turned out to be complete garbage. The FTC stated that Reebok needed to pay a settlement of $25 million for deceptive advertising.

In the News…”

“70 cents of every dollar spent on food stamps goes to bureaucrats” Rep. Michelle Bachmann (R-Minn) (2013)

That quote, from Republican Michelle Bachmann, is completely false. The actual figure is one third of one percent! You can find the real figure here at

Perhaps the most famous case ever of misleading statistics in the news is the case of Sally Clark, who was convicted of murdering her children. She was freed after it was found the statistics used in her murder trial were completely wrong.
