Visualizing citation impact

Michael Bales and his associates at Cornell are working on a new visual tool for citations data. This is an area that is ripe for some innovation. There is a lot of data available but it seems difficult to gain...

In the name of diversity

March 9, 2017

I've said it in Numbersense (the chapter on school rankings), and here it happens again. According to the New York Times (link), Harvard Law School decided to allow applicants to submit GRE test scores instead of LSAT test scores. The announced purpose is to "encourage more students in the United States and internationally from a greater degree of disciplines to apply". The school has a fixed cohort size, 560 per…

Race to the top, Erasmus edition

(This is a submission from reader Lawrence Mayes. Thank you Lawrence!) I came across this unusual graphical representation of the destinations of scholarship students: [Kaiser here: The charts are hidden inside an annoying Flash app and it seems that the...

Sorting out the data, and creating the head-shake manual

Yesterday's post attracted a few good comments. Several readers don't like the data used in the NAEP score chart. The authors labeled the metric "gain in NAEP scale scores" which I interpreted to be "gain scores," a popular way of...

Involuntary head-shaking is probably not an intended consequence of data visualization

This chart is in the Sept/Oct edition of Harvard Magazine: Pretty standard fare. It even is Tufte-sque in the sparing use of axes, labels, and other non-data-ink. Does it bug you how much work you need to do to understand...

The idol worship of objective data is damaging our discipline

October 28, 2016
By

In class last week, I discussed this New York Times article with the students. One of the claims in the article is that the U.S. News ranking of colleges is under threat by newcomers whose rankings are more relevant because they more directly measure outcomes such as earnings of graduates. This specific claim in the article makes me head hurt: "If nothing else, earnings are objective and, as the database…

Why are GMAT scores going up?

October 11, 2016
By

In Chapter 1 of Numbersense (link), I went through an extensive list of shenanigans that can be used to trick the rankings of colleges and graduate schools. One of them is to allow students to submit the maximum of repeated sittings of GREs, LSATs, GMATs, etc. This tactic is unabashedly headlined in a recent Wall Street Journal article, "Test Redos Give GMAT Scores a Lift." (link) In the print edition,…

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…

Myths of Data Science and Analytics

April 11, 2016

Last week, I gave some brief remarks at the INFORMS New York Metro Student-Practitioner Forum (link), attended by a large group of enthusiastic students eager to enter the field of data science and analytics. (By the way, if you are at the INFORMS Analytics Conference in Orlando, come and find me. I am speaking on Ethics on Tuesday morning.) I told the students that it is not too early to…

Statistics report raises mixed emotions

It's gratifying to live through the incredible rise of statistics as a discipline. In a recent report by the American Statistical Association (ASA), we learned that enrollment at all levels (bachelor, master and doctorate) has exploded in the last 5-10...
