Same money, different counting strategies

Condé Nast Traveler got 70 people from 70 different countries to count money on camera. Many times I found myself wondering, “Why would you ever do it like that?” There’s a metaphor for data and its interpretation somewhere in there. Tags: metaphor, money

History of the word ‘data’

Sandra Rendgen describes the history of “data” the word and where it stands in present day. All through the evolution of statistics through the 19th century, data was generated by humans, and the scientific methodology of measuring and recording data had been a constant topic of debate. This is not trivial, as the question of how data is generated also answers the question of whether and how it is capable...

Finding the best Mario Kart character, statistical speaking

Henry Hinnefeld answers the age-old debate of which Mario Kart character is best, using data as his guide. Some people swore by zippy Yoshi, others argued that big, heavy Bowser was the best option. Back then there were only eight options to choose from; fast forward to the current iteration of the Mario Kart franchise and the question is even more complicated because you can select different karts and tires...

Visual introduction to bias in machine learning

A few years ago, Stephanie Yee and Tony Chu explained the introductory facets of machine learning. The piece stood out because it was such a good use of the scrollytelling format. Yee and Chu just published a follow-up that goes into more detail about bias, intentional or not. It’s equally worth your time. (Seems to work best in Chrome.) Tags: machine learning, scrollytelling

Blockchain visually explained

I feel like I was supposed to know what blockchain is a while ago, but I’ve only had a hand-wavy explanation on hand. And it wasn’t a very good one.

Vector paths of meaning between words and phrases

Benjamin Schmidt, an assistant professor of history at Northeastern University, explored the space between words and drew the paths to get from one word to another. The above, for example, is the path between Seinfeld and Breaking Bad. Using Google News as the corpus, the steps: Take any two words. I used “duck” and “soup” for my testing. Find a word that is, in cosine distance, between the two words:...

Math gender gap bigger in richer school districts

This is quite the scatterplot from Claire Cain Miller and Kevin Quealy for The Upshot. The vertical axis represents by how much girls or boys are better in standardized tests; the horizontal axis represents wealth; each bubble represents a school district; and yellow represents English test scores, and blue represents math test scores. The result: a non-trend up top and a widening gap at the bottom. Tags: gender, math, school,...

Ancient Earth globe shows where you were located 750 million years ago

In a spin on the view of ancient Earth and the shift of the continents, Ian Webster made a globe where you can enter a location and see what was in that spot millions of years ago. Not all addresses were working for me at the time, so you might want to try a major city if it’s doing the same for you. [via kottke] Tags: Earth, tectonic plates
