“Spurious Correlations” website

If you have studied statistics then you must be aware of the statement, “correlation does not imply causation”. This statement essentially means that we cannot legitimately deduce a cause-and-effect relationship between two variables solely on the basis of an observed association or correlation between them. If you need examples to support this statement then you should visit “Spurious Correlations” website at

Created by Tyler Vigen, this website documents examples of what are best described as spurious relationships. These are the relationships in which two events have no causal link, but still appear to due to either a coincidence or a third, confounding variable. The site shows the charts on which two variabes are plotted against the time line along with Pearson correlation (r) value. The site also allows us to discover new correlations. We tried the same and found the following correlations.

“Apple stock price on January 1 correlates” with “Worldwide commercial space launches” with r=0.945948
“Apple iPhone sales” correlates with “Per capita consumption of american cheese (US)” with r=0.999421
“UK: Military defense spending” correlates with “Number of people killed by hornets, wasps and bees in US” with r=0.999436

Needless to say, there are apparently no cause-and-effect relationship between these variables!

How Google Works: 50 Ideas

In September 2014, Eric Schmidt (ex-CEO of Google, current Executive Chairman, Alphabet), Jonathan Rosenberg (ex-head of products at Google; current advisor to the CEO, Alphabet), and Alan Eagle (director of executive communications at Google) published a book titled “How Google Works”. This book provides insights into functioning of Google. But more than describing how things work at Google, the authors have attempted to provide guidance on how to manage new-age companies that would employ “smart creatives”. The advice is given for almost all aspects of business, starting from culture to strategy to decisions to innovation.

Not exactly the summary but somewhat the essence of this book is available in the web article on “How Google Works: 50 Ideas“. Written by the authors of the book, this article can give an inside look at the authors’ 50 ideas that inspired the book. A must-read for every business manager!
