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…

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…

Where is NYT’s data science team when you need them?

The management at New York Times was smart enough to create a data science team but apparently the newsroom has not yet been exposed to STAT 101. Today, NYT printed this headline: "Top C.E.O. Pay Fell -- Yes, Fell -- in 2015" (link to article). I immediately thought, not so fast, are they talking about average pay or median pay. Anyone who has taken STAT 101 knows that when analyzing…

Tip of the day: don’t be Theranosed

May 23, 2016

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):…

Law versus ethics: how the new overtime pay rule will play out

May 18, 2016
By

In any discussion of ethics , someone is bound to bring up the law: it is okay to do something if something is not against the law. The logical conclusion of this belief is that ethics is irrelevant in the presence of the law. The recent stories relating to minimum wage and the overtime pay rule changes (for example, link) argue strongly against such a point of view. The law…

The many-faced area chart is not usually your best choice

I found this chart about the exploding U.S. debt levels in ZeroHedge (link), sourced from Citibank. The top line story is pretty easy to see: total debt levels have almost reached the peak of the 1930s. (Ignore that dreadful labeling...

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…
