Running data centers and IT is so many times about making decisions related to risks. BBC has an article on risk and uncertainty.
Here is a test the BBC article references. Dr. Edward Cokely is the sponsor of the research.
I took the test at 3a in the morning when I couldn't go back to sleep. Pleasantly I got a perfect score. The study cautions me I should still take care and may want to double check your calculations or seek additional advice when ic comes to important decisions involving risks and statistics.
These are good words of advice for data center projects. It would be interesting if everyone took the test to give them feedback on their statistical and risk literacy.
