Last week I told you about an article that brought back some old memories on how to lie with statistics.
One of the most common tricks used is to show small changes as huge by not using zero as the base in a diagram. This trick is used all the time in newspapers.
And these are only a few tricks possible that works well on graphs. You also have the option of excluding important data. For example you can say that "the risk of being infected by [insert your choice of horrible disease here] is 50% higher if [insert something you like to do here]". But what if the initial risk was only 0.01%. That means the increase risk is 0.015%. That does not sound so horrible does it? But it is 50% higher risk...
