Comment on Beginners Guide to Maths and Stats behind Web Analytics

WTF? This was a somewhat incoherent list of "stats stuff"; I especially liked the equation:

                signal
   confidence = ------  x  \sqrt(sample size)
                noise
                
(none of the terms in the 'equation' were defined beforehand) which was led into by 'so when someone says “is your result statistically significant?” then it means he is really asking “What is the likely hood that your result has not occurred by chance”' No no no no no no no no no no non.

Edit: corrected despair-induced typos.
