The SELF SELECTING SAMPLE.
(Thanks Ivy for the No 1 rocket.)
Newspaper and magazine editors urge their readers to ‘click-on our website poll’ and then they publish the results in the next issue. The newspaper may learn about their readership. This is useful information for marketing but otherwise useless. It’s like asking hat wearers if they wear hats. Let me guess the answer? D’uh!
Included here are some results of two self-selecting surveys, which not only reveal the standard useless statistics but also some highly questionable numerical outcomes. In the Esquire Magazine Survey of Drinking (Sept 2010) 82% of their readers, who were willing to answer a survey about their drinking habits (Whereby, for some reason. 1 beer = 2 drinks), have a University Degree or higher (Or, maybe, 50% of them lie!!!!) and in the Health and Fitness (Oct 2010) magazine survey - Guess what? – magically the numbers for all options add up to 100%. Neat! Didn’t anyone fit more than one category? (Assuming all readers of Health and Fitness mag who are bothered enough to answer a survey on fitness do some exercise.)
