Depicting imbalance, straying from the standard chart

My friend Tonny M. sent me a tip to two pretty nice charts depicting the state of U.S. healthcare spending (link). The first shows U.S. as an outlier: This chart is a replica of the Lane Kenworthy chart, with some...

Graphical inequity ruins the chart

This Economist chart has a great concept but I find it difficult to find the story: (link) I am a fan of color-coding the text as they have done here so that part is good. The journalist has this neat...

Know your data 20: trust and distrust in our surveillance society

September 5, 2016
By

A very important article from the Times starts with the following sentence: Want to invisibly spy on 10 iPhone owners without their knowledge? Gather their every keystroke, sound, message and location? That will cost you $650,000, plus a $500,000 setup fee with an Israeli outfit called the NSO Group. In the U.S., there is a disconnect between a populace whose distrust of government is at an all-time high and the…

Thank you Buzzfeed for noticing us humans

My friend John R. sent me this excellent Buzzfeed feature on music playlists. Here are some choice quotes to whet your appetite: In 2014, when Tim Cook explained Apple’s stunning $3 billion purchase of Beats by repeatedly invoking its “very rare and hard to find” team of music experts, he was talking about these guys. And their efforts since, which have pointed toward curated playlists (specifically, an industrial-scale trove of…

Quote of the month

In a post titled "GIGO" (for those who don't like acronyms, Garbage In, Garbage Out), Andrew Gelman wrote this gem: as long as the “garbage out” gets media attention, there will always be somebody willing to supply the “garbage in.” The general drift of that post, and the previous one that led me to it, is a critique of the management consulting industry. Having worked in that industry earlier in…

Brexit, Bremain, the world did not end so dataviz people can throw shade and color

Catching a dose of Alberto Cairo the other day. He has a good post about various Brexit/Bremain maps. The story started with an editor of The Spectator, who went on twitter to make the claim that the map on the...

Know your data 19: don’t tell me you are 2 blocks away when you are 20 blocks away

Well, it didn't take long but private investigators have found the next big thing: Big Data. Bloomberg reported on a company called IDI, who sells our data to private investigators. (link) Unfortunately, this article is short on details and long on sensationalized catchphrases ("Every move you make. Every click you take...") The CEO of IDI boasted that "We have data on that 21-year-old who’s living at home with mom and…

Apple Watch users overwhelmingly satisfied, says a survey of satisfied users

As word of plummeting sales of Apple Watch spread around last week, an entrepreneur went on Medium to sing a different tune: his survey apparently uncovered a "paradox" - Apple Watch users are "overwhelmingly satisfied, yet not recommending" the product. The "overwhelming" bit comes from this chart: This data portray a hugely successful product in which almost nobody expressed any negative feelings. This next chart is even more impressive. Apparently,…

Ethical dilemmas in data science and analytics

About half a year ago, when my article on ethics in data science appeared on Harvard Business Review, the second half of the piece was dropped. In the omitted section, I had designed a poll inviting readers to opine on several ethical dilemmas facing real-world data analysts. In April, Manoj Chari read my HBR article and kindly invited me to speak on the subject at the INFORMS Analytics Conference, and…

Your emails are being read (though I also think this is a hoax)

June 20, 2016
By

CNBC reports that Goldman Sachs flags employee emails based on a long list of "offending" phrases. If an employee types a profanity, apparently a window pops up to confirm that the person really truly wants to say that word. The other objective given is to detect fraudulent behavior. The list they published apparently came from 2008, so very aged, but I think it is a hoax. Many of the terms…
