A funny, enlightening article from the British Medical Journal BMJ, from 1999. Evidence vs Eminence Based Medicine
Be sure to check out the table at the end.
Another entertaining article about
Evidence over Eminence in Medicine and Healthcare
Not British, but amusing just the same.
Here is a link to a very useful statistic calculating spreadsheet called “Dag-Stat”. With this spreadsheet you can perform many useful calculations without resorting to SPSS or other “Statistical Packages”. It was created by Andrew Mackinnon, and is provided free on his website: www.mhri.edu.au/biostats/DAG_Stat
Marley Watkins has created a plethora of small standalone apps for statistical calculation, and offers them freely in both windows and mac formats at: www.public.asu.edu/~mwwatkin/Watkins3.html (be sure to scroll down the page.)
I will be adding links to more tools like these soon. Please feel free to suggest others as well.
