I hate bad surveys. a recent survey about mobile phone use came up with the conclusion that mobiles cause brain cancer. Looking at it in very little detail reveals that the survey has 4 classes.
1 .Probably Carcinogenic
2. Possibly Carcinogenic
3. Not Classifiable
4.
5.Probably not Carcinogenic
This sort of survey annoys me.. what about Possibly not Carcinogenic - you can't have a survey without a sit on the fence option and if you do - you have to have a balance either side. So if this survey was conducted sensibly would we know: are we borderline thinking Probably or borderline possibly (as there is a none existent number 4). GRRRRR!!!
