Who Hires These People?

And now, from Business Insider, an example of statistics abuse. There are so many things wrong with this that I don't even know where to start.

Sample size: 216, all from Minneapolis
Sample does not reflect market: 36 Android users (17%)? A 17% share is about 1/3 of what Android actually has in the market. 61 Blackberry users (28%) is just laughable.
The number of Androids actually holds constant in the question "which phone will you buy next?" which seems to imply that apart from the 47% (17 users) that stick with Android, the other 19 will be almost entirely replaced by Blackberry users. Because you know, that makes a whole lot of sense.

In fact I don't even know why they're trolling Android in the first place. If we ignore for a moment that the statistics are completely useless and try to gain some sort of meaningful conclusion from this, it should be "Blackberry owners ready to ditch their phones." It makes no sense that they should be focusing on Android here if it only constitutes 17% of the market. The "analyst" is well aware that this is not the case, and that's why he is focusing on the Android users. If he felt Android was not any more relevant than the 17% would suggest, he wouldn't have mentioned it at all, like Windows.

I can draw a conclusion just as meaningful from the comments on the article: based on a survey of 100 commenters on that article, 100% of the world thinks the writer and "analyst" are completely inane.

Look carefully and you will find similar examples in the media in just about any field.
