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. 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.

Beautiful Word Clouds 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". 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. An unfortunate circumstance for the student is that the two schools use the same terms, but in different ways, and often refuse to recognize the alternative usage.

37 Data-ish Blogs You Should Know About You might not know it, but there are actually a ton of data and visualization blogs out there. I'm a bit of a feed addict subscribing to just about anything with a chart or a mention of statistics on it (and naturally have to do some feed-cleaning every now and then). In a follow up to my short list last year, here are the data-ish blogs, some old and some new, that continue to post interesting stuff. Data and Statistics By the Numbers - Column from The New York Times visual Op-ed columnist, Charles Blow, who also used to be NYT's graphics director.Data Mining - Matthew Hurst, scientist at Microsoft's MSN, also the co-creator of BlogPulse.Statistical Modeling - We might disagree on certain things, but Andrew's blog is one of the few active pure statistics blogs.The Numbers Guy - Data-minded reporting from Carl Bialik of the Wall Street Journal.Basketball Geek - Like statistical analysis and basketball?

(french) Boîte à moustaches Un article de Wikipédia, l'encyclopédie libre. Dans les représentations graphiques de données statistiques, la boîte à moustaches (aussi appelée diagramme en boîte, boîte de Tukey ou box plot) est un moyen rapide de figurer le profil essentiel d'une série statistique quantitative. Elle a été inventée en 1977 par John Tukey, mais peut faire l'objet de certains aménagements selon les utilisateurs. Son nom est la traduction de Box and Whiskers Plot. Principe[modifier | modifier le code] Il s'agit de tracer un rectangle allant du premier quartile au troisième quartile et coupé par la médiane. ), voire aux 5e et 95e centiles. Comparaison de deux diagrammes en boîte à moustaches avec- pour la boîte inférieure : Q1 = 3, M = 7, Q3=12, - pour la boîte supérieure : Q1 = 7, M = 9, Q3=12, Historique[modifier | modifier le code] Dans les diagrammes en boîte de Tukey, la longueur des « moustaches » vaut 1,5 fois l’écart interquartile. On les y désigne aussi sous les vocables de boîtes à pattes ou Box Plot.

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. We’re making indiemapper free so that it can continue to exist as a useful tool for map-makers while freeing us up to be as awesome as possible at our custom cartography business. 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. The alt tag for each image gives the name of the character. Students who are just learning the symbols can move the mouse to any symbol to get a brief reminder of its name. 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. 6} {x | x=1 or x=2 or x=3} .

Junk Charts This post is part 2 of an appreciation of the chart project by Google Newslab, advised by Alberto Cairo, on the gender and racial diversity of the newsroom. Part 1 can be read here. In the previous discussion, I left out the following scatter bubble plot. This plot is available in two versions, one for gender and one for race. The story appears to be a happy one: in many newsrooms, the leadership roughly reflects the staff in terms of gender distribution (even though both parts of the whole compare disfavorably to the gender ratio in the neighborhoods, as we saw in the previous post.) Unfortunately, there are a few execution problems with this scatter plot. First, take a look at the vertical axis labels on the right side. I find this decision confounding. The horizontal axis? Here is the same chart with improved axis labels: Re-labeling serves up a new issue. The solution, as shown below, is to shift the vertical gridlines by 5% so that the 45-degree line bisects every grid cell it touches.
