The cartoon guide to Statistics

October 3, 2010 Marco education, Extra, statistics

Cover of the book: the cartoon guide to statistics

This is one of the best and funniest book I have ever read! :) It explains in such an easy way very complex things! A perfect book that teaches you while making you laugh :)

Generally reading a book for me it takes ages, but i finished this one during a flight London-Milan (return flight… yes) :)

Saying that it is funny it is not enough!

Learning statistics through this book will be like eating nutella (ps I love nutella) ;) Of course, it will be a basic course, but honestly speaking, if you already have a basic understanding, you will enjoy this book very much.

Here is just page number 1 :) Have a laugh :) (Click on the image below to enlarge).

What is statistics

219 pages of wonderful entertainment. Actually it is not a book.. it is more like a show! :)

The different stories are so live, so cool… so funny!

It covers from what is statistics, to probability, random variables, sampling, confidence intervals, hypothesis testing, regression.

Honestly a very well thought and written book. Thank to the genius of Larry Gonick and Woollcott Smith.

Highly recommended!

Logo Google ChromeTwo months are already gone since the launch of Google Chrome. Its market share still around 3% (source: w3school accessed on the 6th of November 2008). From the data available, we can see how IE still losing market share. Users who leave IE6 (-2.1%) are more than the ones who move on IE7 (+0.6%). The winner in this battle still Firefox that gained 1.4% of the market share.

One of the reasons why Google Chrome’s market share isn’t increased yet it is probably because of the missing google toolbar. Many users still complaining about this problem and most of them said they won’t use Google Chrome until the Google toolbar is available.

Ciao :)

Google Chrome runs quickly: already more than 3% of the market share

Logo Google ChromeGoogle Chrome has been launched less than a month ago and has already reached 3.1% of the market share (source: w3school accessed on the 4th of October 2008).

If this trend continues (and probably it will), in few months Google Chrome will be the leader of the market! :) I bet on it!

Only a recommedation:

People still complaining about the missing google toolbar.  Google Chrome is the best browser I have ever tried: fast, clear, and usable. But please Google Guys… the toolbar is absolutely needed. And I really hope you will come up with a wonderful original Google Chrome Toolbar… something like the one I hypothesized in one of my previous post: Google Chrome in the 3 most used browsers: how long will it take?

Or maybe something better, something that we human beings can’t neither imagine! ;)

Ciao :)
