Statistical Visualization For his book The Visual Miscellaneum, David McCandless, along with Lee Byron, had a look at breakups on Facebook, according to status updates. They looked for the phrase "we broke up because" in status updates, and then graphed the frequencies over time. Why they couldn't just look at updates to relationship status, I'm not sure. Notice the peak leading up to the holiday season and spring cleaning. Then there's the people who think it's a funny April Fool's joke to say the broke up with their significant other. Finally, there's the highlight of Mondays, which you might lead you to believe that people like to call it quits during the beginning of the week. [Information is Beautiful | Thanks, Elise]

Visual Mapping.com Monophyletic, Polyphyletic, & Paraphyletc Taxa Concepts of monopoly, polyphyly, & paraphyly A taxon (pl. taxa) is any group of organisms that is given a formal taxonomic name. Loosely, a monophyletic taxon is one that includes a group of organisms descended from a single ancestor , whereas a polyphyletic taxon is composed of unrelated organisms descended from more than one ancestor. These loose definitions fail to recognize the fact that all organisms are related, therefore any conceivable group is logically "monophyletic". In modern usage, a monophyletic taxon is defined as one that includes the most recent common ancestor of a group of organisms, and all of its descendents [as in (a)]. Such groups are sometimes called holophyletic. Well-known monophyletic taxa include Mammalia and Aves (modern birds), recognizable as all furry and feathered vertebrates, respectively. Taxonomists tend to fall into two schools, "Evolutionary" or "traditional" systematics versus "Phylogenetic" or "cladistic" systematics.

Cytoscape: An Open Source Platform for Complex Network Analysis and Visualization International Statistical Literacy Project home The International Statistical Literacy Project (ISLP) is a project initiated by the International Association for Statistical Education➶ (IASE), which is the education section of the International Statistical Institute➶ (ISI). The main objective of the ISLP is to contribute to promoting statistical literacy across the world, among young and adults, in all walks of life. To this end, we provide an online repository of international resources and news in Statistical Literacy, international activities to promote the resources and the individuals and institutions behind them, and outreach activities to increase awareness. Contact the IASE Executive➶ or the ISLP Director Reija Helenius➶ by e-mail if you have any questions. New Country Coordinator in Finland - Welcome to the ISLP team Jaana Kesti!

Beautiful Word Clouds indiemapper is free - Axis Maps Blog by David Heyman on January 5, 2012 With the start of 2012, we’ve decided to make indiemapper free to use. Since indiemapper launched in 2010, our business has grown and changed to where supporting and maintaining indiemapper is no longer a major part of what we do at Axis Maps every day. To allow us to give it away for free, we’re scaling back what indiemapper does. We’re really happy about this change and we hope you are too. Launch indiemapper Mathematical Background This web page is a revised and extended version of Appendix A from the book Conceptual Structures by John F. Sowa. It presents a brief summary of the following topics for students and general readers of that book and related books such as Knowledge Representation and books on logic, linguistics, and computer science. Note: Special symbols in this file that are outside the Latin-1 character set (ISO 8859-1) are represented by a .gif image for each character. 1. Elementary or "naive" set theory is used to define basic mathematical structures. Curly braces are used to enclose a set specification. This specifies a set consisting of the four integers 1, 97, 63, and 12. If the set is very large, like the set of all mammals, a complete listing is impossible. {x | vertebrate(x) and warmBlooded(x) and hasHair(x) and lactiferous(x)} This specification may be read the set of all x such that x is vertebrate, x is warm blooded, x has hair, and x is lactiferous. 6} {x | x=1 or x=2 or x=3} .
