I wasn't pointing out his spelling error but questioning the use of a chequebook. Thought i'd stepped back in time, last time i used a chequebook for a takeaway i was writing ones that bounced whilst i was a student at Uni back in the previous century. For what its worth my spelling is atrocious but i'm glad I managed to help you in this particular matter

That was referring to how stats van be manipulated and not mobile phone use.
You quote to the link - http://www.informationweek.com/news/212201254 For research to be valid, it must be independant (who commissioned it? We do not know), reasonable sample size (41 is too low) and repeatable - you can repeat and reproduce the phone calls by using a taped message but human interaction?
How many of the 41 pairs were told of the nature of the reasearch? If you were part of the research, how animated would you be if you were the passenger? If you, as passenger, would distract the driver whilst he was on the phone in order to prove your point?

No, for research to be valid it needs to be scientifically controlled.

41 is ok for a sample if it involved physical testing and is open to peer review. For statistical analysis you'd aim for much higher, in the thousands.

Not true I'm afraid. There's plenty of statistical tests where you don't need a large sample size.

Bashing your face repeatedly into a solid object such as a wall or a tree will cause discomfort, swelling and eventually a loss of conciousness.

Number of test cases needed to prove the above hypothesis beyond any reasonable doubt = 1 (although the more astute amongst us probably wouldn't need that many)
