Should I tell students that the maximum score in the class is 137?

May 22, 2015

This op-ed by Richard Thaler caught my attention because I have a similar experience. In my statistics classes, I have noticed a pattern: if the mid-term exam is hard, with a lower average score (say 75-80%), the students look crestfallen and feel that they did not learn; eventually, when it comes to evaluating the instructor, I receive lower grades, with comments indicating that I have not taught them properly to…

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…

Composite ranking and numbersense

Chapter 1 of Numbersense (link)uses the example of U.S. News ranking of law schools to explore the national pastime of ranking almost anything. 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…
