Monday after Thanksgiving, see you at the Data Visualization Meetup

My little analytics training startup, Principal Analytics Prep, is proud to sponsor the next meeting of the Data Visualization New York Meetup, organized by the indefatigable Naomi Robbins. The Meetup, to be held on November 26, 2018 (Monday), headlines NYU professor, Kristen Sosulski, who will discuss the “business case for data visualization”. Click here to register.

Naomi is a long-time friend. I reviewed and recommended her book on Creating More Effective Data Graphics in 2008. This is still a useful reference to some key concepts, presented in a clean, easily digestible format.

The keynote speaker, Kristen, has just published Data Visualization Made Simple, described as a “top book for computer science students.” I am very much looking forward to her talk because the subject speaks to the core of the mission of Principal Analytics Prep: placing data science & analytics in the context of the entire enterprise.

That’s why my bootcamp and training programs emphasize the Three Pillars: computing, statistics, and business. Our instructors are practitioners with 10 to 30 years of learning from real-world implementation of models and systems used by forward-thinking, data-driven organizations.

The Spring 2019 cohort of our Certified Data Specialist bootcamp is open for applications. If you're looking to transition your career into data science and advanced analytics, check us out. Here are some of the great things our alums have said about the program. Take advantage of the early admit deadline by December 10, 2018. Click here for more information.

I'm excited to hear what Kristen has to say about using data visualization in the business world. Kristen's website is here. She teaches at NYU's Stern School of Business, and describes herself as a computer scientist. Here's the link to the Amazon page. Unfortunately the page is not very informative about the book's content. The table of contents is minimalist ("The Design", "The Audience", etc.). I will report back on what she spoke about after the Meetup.

 

 

Webinar Wednesday

I'm delivering a quick-fire Webinar this Wednesday on how to make impactful data graphics for communication and persuasion. Registration is free, at this link.

In the meantime, I'm preparing a guest lecture for the Data Visualization class at Yeshiva University Sims School of Management. The goal of the lecture is to emphasize the importance of incorporating analytics into the data visualization process.

Here is the lesson plan:

1. Introduce the Trifecta checkup (link) which is the general framework for effective data visualizations
2. Provide examples of Type D data visualizations, i.e. graphics that have good production values but fail due to issues with the data or the analysis
3. Hands-on demo of an end-to-end data visualization process
4. Lessons from the demo including the iterative nature of analytics and visualization; and sketching
5. Overview of basic statistics concepts useful to visual designers

On the sister blog about predictive models and Big Data, I have been discussing aspects of a dataset containing IMDB movie data. Here are previous posts (1, 2, 3).

The latest instalment contains the following chart:

The general idea is that the average rating of the average film on IMDB has declined from about 7.5 to 6.5... but this does not mean that IMDB users like oldies more than recent movies. The problem is a bias in the IMDB user base. Since IMDB's website launched only in 1990, users are much more likely to be reviewing movies released after 1990 than before. Further, if users are reviewing oldies, they are likely reviewing oldies that they like and go back to, rather than the horrible movie they watched 15 years ago.

Modelers should be exploring and investigating their datasets before building their models. Same thing for anyone doing data visualization! You need to understand the origin of the data, and its biases in order to tell the proper story.

Hello to St. Louis readers

I'll be hosting a Data Visualization workshop at the Digital Media Marketing Conference in St. Louis, Missouri on Thursday. Here is the link to their website.

The workshop is arranged from three themes: Appreciating, Conceptualizing, and Improving. There will be several hands-on exercises.

If you are a reader in St. Louis, and would like to meet up, email me.

Posting this week will be light because of various commitment. I may put something up later this week.

One of my students pointed me to this Medium article about a NYT chart. Well worth reading.

 

Numbersense, in Chinese and Japanese

This is a cross-post on my two blogs.

The new year brings news that my second book, Numbersense: How to Use Big Data to Your Advantage has been translated into Chinese (simplified) and Japanese. Here are the book covers:

In Chinese, the title reads: "Say No to Fake Big Data". Captures the sentiment of the book pretty well, I must say.

I have no idea what the Japanese title means. Perhaps a reader can help me out here.

The Japanese version is available here or here.

The Chinese version is here.

The English version is here.

The snow made me do it - California, here I come

California readers: here's a chance to come meet me. I am giving talks in San Diego (Feb 3) and San Mateo (Feb 5) next week, courtesy of JMP. Free registration is here. 

These talks are related to two ongoing projects of mine: the first project is to create a theory of data visualization criticism. How can we use precise language to describe our reactions - good and bad - to data visualization work? The second project is surrounding how to find stories from a mass of data.

 

I'd love to meet some of you on the West Coast who are fans of the blog. Please also forward this announcement to your friends or colleagues who might be interested.

Three good charts

Alberto Cairo, Stephen McDaniel and I were asked about our "favorite" data visualization at the Qlik Conference this week. Stephen wrote up our answers here.

A little something while I'm away

Note: This is cross-posted to both my blogs.

I have been on vacation. Regular posts will resume next week. Before then, here is a little something for you.

ASA News recently asked me to describe "a day in the life of" a business statistician. My response is here, together with responses by two others. 

As a statistician, I am worried about describing an "average" day for an "average" statistician. Better think of this as a day selected from a normal distribution that is close to its center.

If you have even more time, Andrew Gelman thinks these six posts are worth re-reading.

Happy weekend!

 

Me and Alberto Cairo in one room tomorrow

I have been a fan of Alberto Cairo for a while, and am slowly working my way through his great book, The Functional Art, which I will review soon.

Thanks to the folks at JMP, the two of us will be appearing together in the Analytically Speaking webcast, on Friday, 1-2 pm EST. Sign up here. We are both opinionated people, so the discussion will be lively. Come and ask us questions.
