Some data science principles from Gelman, Rosling and me

I discovered Hans Rosling's Gapminder work when I first started Junk Charts almost ten year ago, with this series of posts. So I was very excited to meet Hans yesterday at the Data, Children and Post-2015 Agenda Event hosted by the UNICEF Data and Analytics Section. And he gave a marvellous talk. I came away touched in equal parts by his humanity, the animated passion for his subject, and the…

Cluster analysis in the classroom

I am a guest at the New School's Journalism + Design program this semester. The students conducted interviews about the question of what makes someone famous. Their interviewees were asked to name five famous people. We had images of these people up on the wall. Then, we put the pictures into clusters. We tried two different ways of doing it. At the end, we compared our result to what a…

Since there is no objective standard for the "correct" ranking, it is pointless to complain about "arbitrary" weighting and so on. Every replacement has its own assumptions. A more productive path forward is to understand how the composite ranking is created, and shine a light on the…

Consider this paragraph from a FiveThirtyEight article about the small-schools movement (my italics): Hanushek calculated the economic value of good and bad teachers, combining the “quality” of a teacher — based on student achievement on tests — with the lifetime earnings of an average American entering the workforce. He found that a very high-performing teacher with a class of 20 students could raise her pupils’ average lifetime earnings by as…

How students can improve their final grade without studying even more

Cross-post on my two blogs Here is something different: I wrote a piece on exam-taking tips. It's on a new website, Cafe, which has lots of good (non-quant) reads. The motivation for the piece is my observation that most American students are not taught how to take exams. As a professor, I notice that many students get lower scores than they deserve because of this. In this article, I describe…
