April 11, 2016
By

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...

The analytics talent gap: a hiring manager’s perspective

October 20, 2015
By

We all know that data science/business analytics is booming. Lots of companies are creating lots of jobs. However, the barriers to entry into this field are substantial. In an article for rSQUAREedge, I summarized my own experience as a hiring manager. A data analyst needs intuition about data, which requires practical experience. Certain skills, like web analytics and A/B testing, are not academic research areas, and are not unusually taught…

This map appeared in Princeton Alumni Weekly: Here is another map I created: If you think they look basically the same, you got the point. Now look at the data on the maps. The original map displays the proportion of...

Making stuff up to get published in NYTimes

Reader/friend Tom B. knows about my interest in grade "deflation" policies, and proceeds to ruin my breakfast by sending me a link to this ludicrous "letter to the editor" by a high-school counsellor (link). It starts with a made-up assertion: As the new academic term starts, I’m rooting for this to be the year when students start getting the grades they rightfully earn without high schools and colleges manipulating numbers…

September 9, 2015

I wished I had a chance to take Gene Woolsey's class. Woolsey was a major personality in Operations Research, and from reading a set of remembrances in ORMS Today (June 2015), I learned that he was also an amazing teacher. And no one in his class made spelling errors! How cool is that. Well, I don't know if no one ever made a spelling error but I bet that the…

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

May 22, 2015
By

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…

Shaking up expectations for pension benefits

Ted Ballachine wrote me about his website Pension360 pointing me to a recent attempt at visualizing pension benefits in various retirement systems in the state of Illinois. The link to the blog post is here. One of the things they...
