The tutorial on correlation coefficients is complete and will be out at some point next week. It is also a response to certain “rebuttal”.

After reading it you will understand why statistics is a loss for SEOs, at least for those SEOs that have embraced the quack Science from SEOMOZ.

There is a surprise there for those that misquote search results and abstracts of research papers they have never read thoroughly: That’s the signature of sloppy “research”.

Until then, Happy 4th of July.
