In this assignment, the focus was to practice data cleaning. Students suggested questions to build a class survey, to get to know the interests of other class members, and then completed the composed survey. After cleaning the data, a few summary plots of interesting aspects of the data were made. There are some common mistakes that rookies often make when constructing data plots: packing too much into a single graphic, leaving categorical variables unordered, reversing norms for response and explanatory variables, conditioning in wrong order, plotting counts when proportions should be the focus, not normalizing by counts, using a boxplot for small sample size.

In the days since the death of Justice Antonin Scalia, there has been a lot of discussion on what is going to happen now - whether President Obama should or should not nominate a candidate to fill the vacancy in the supreme court.

This week I have been visiting the Department of Statistical Sciences at Cornell University. This is the home of many venerable statisticians. At first sight it appears that statisticians are spread all over the university, and technically they are because funding comes from many directions, but almost all are actually located in a suite in Comstock Hall. Professor Paul Velleman is one of the pioneers of data-centrist thinking about statistics. He produced the software called DataDesk in the early 90s that some saw as rivaling LispStat and particularly JMP for introductory statistics classes.

This week I have been visiting the new Center for Statistics and Applications in Forensic Evidence. The center involves four universities, CMU, ISU, UC-Irvine, U.

The speaker list included Barry Scheck (Co-Founder, The Innocence Project), Jo Handelsman (The White House Office of Science & Technology Policy), Philip Dawid (Emeritus Professor of Statistics, University of Cambridge), Anil Jain (Michigan State University) and Stephen Feinberg (CMU).
