Meanwhile, there are a good number of people interested in entering the field but keep bumping into walls. Hiring managers like to hire experienced people for a host of reasons, including the fear of other hiring managers poaching their trained employees. For a number…

One statement employing two resistance tactics to fend off the data

March 10, 2017
By

I want to parse this statement by new EPA Chief Scott Pruitt, as quoted in this New York Times article: I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see. I'm not going to talk about…

Reading Everything is Obvious by Duncan Watts

In his book, Everything is Obvious (Once You Know the Answer): Why Common Sense Fails, Duncan Watts, a professor of sociology at Columbia, imparts urgent lessons that are as relevant to his students as to self-proclaimed data scientists. It takes only nominal effort to generate narrative structures that retrace the past, Watts contends, but developing lasting theory that produces valid predictions requires much more effort than common sense. Watts’s is…

Deep thinking about your data

In the on-going series of posts about the IMDB dataset, from Kaggle, I have so far looked at several of the scraped variables, including the number of faces on movie posters (1, 2), plot keywords (3), and movie rating by title year (4). In this post, I tackle the variables resulting from a data merge between IMDB and Facebook. These columns have names like "Director Facebook Likes", "Actor 1 Facebook…

Numbersense and government accountability in the new political reality

January 24, 2017
By

You've heard me say often, numbersense is the most important quality for good data analysts; little did I know that numbersense would become the new requirement for healthy American democracy. From the first day in office, the new President is at war with numbers (over attendance figures at his inauguration). But I believe that getting to the bottom of data-driven claims is a bi-partisan issue: while it is obvious that…
