Raining, data art, if it ain’t broke

Via Twitter, reader Joe D. asked a few of us to comment on the SparkRadar graphic by WeatherSpark. At the time of writing, the picture for Baltimore is very pretty: The picture for New York is not as pretty but...

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

June 20, 2016

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…

An example of terrible analytics report design

June 1, 2016
By

In the business analytics universe, the discipline of "business intelligence" is often frowned upon. Business intelligence is primarily generating reports on business metrics, tracking them over time, and producing ad-hoc analyses explaining these trends. People often complain that such work is not challenging and not sexy. There is a stigma that BI work is data dumping. In reality, good BI work is rare and extremely valuable. Horrible BI work is…

Theranos (v): to spin stories that appeal to data while not presenting any data To be Theranosed is to fall for scammers who tell stories appealing to data but do not present any actual data. This is worse than story time, in which the storyteller starts out with real data but veers off mid-stream into unsubstantiated froth, hoping you and I got carried away by the narrative flow. Theranos (n):…

Row-Level Thinking vs. Cube Thinking

Our mental model of a dataset changes the way we ask questions. One aspect of that is the shape of the data (long or wide); an equally important issue is whether we think of the data as a collection of rows of numbers that we can aggregate bottom-up, or as a complete dataset that we can slice top-down to ask … Continue reading Row-Level Thinking vs. Cube Thinking

Dreadful analysis shows the importance of numbersense

May 9, 2016
By

Last year, Gizmodo capitalized on the fallout from the Ashley Madison hacking scandal and published a sensational article claiming the website that, if you haven't heard, promotes adultery, has "almost no" real women on it. The subtext is that millions of gullible, disloyal males were paying monthly fees to the website to do nothing or, cue the laugh track, to converse with "badly-designed robots." These men, according to Gizmodo, were…

April 11, 2016

Last week, I gave some brief remarks at the INFORMS New York Metro Student-Practitioner Forum (link), attended by a large group of enthusiastic students eager to enter the field of data science and analytics. (By the way, if you are at the INFORMS Analytics Conference in Orlando, come and find me. I am speaking on Ethics on Tuesday morning.) I told the students that it is not too early to…

First ask the right question: the data scientist edition

A reader didn't like this graphic in the Wall Street Journal: One could turn every panel into a bar chart but unfortunately, the situation does not improve much. Some charts just can't be fixed by altering the visual design. The...
