Lies, Damned Lies and Statistics
Listen to this article
Whilst reading the latest news headlines on the ABC (Australian Broadcasting Corporation) web site just now, I happened upon what seemed like a rather interesting article entitled Brain fluid draining eases dementia: research. Fascinated, I read on.
...The study investigated 20 patients...71 per cent of our patients improved in memory and mental function and 94 per cent improved in balance and walking...
Hang on a second...71 percent of 20 patients would be...14.2 patients; 94 percent of 20 patients would be...18.8 patients. Huh?
Comments
Perhaps 3 ppl died?
12/17 = 71% (70.6)
16/17 = 94% (94.1)
