How to better communicate election forecasts — in one simple chart
Justin Gross | Monkey Cage blog [Washington Post]
November 29, 2016
Most folks were surprised by the results of the 2016 Presidential election and this was in part due to some of the rosy forecasts by some of the poll aggregators, like Huffington Post. But, even when a site had a forecast with a 30% chance of Trump winning, most people have trouble understanding that a Trump victory was possible. The explanation:
But certain representations of probability are more readily grasped than others. In particular, we have trouble understanding risk in terms of the “percent chance” but we do better when simple raw numbers of different outcomes are depicted visually.
Solution: Show the risk as a “Risk Visualization Theater.” Below are the representations of forecasts of victory for Trump via FiveThirtyEight, NYT Upshot, and Huffington Post Pollster. The filled theater seats (in black) represent the chance of a Trump victory. Clearly, the chance of that event happening don’t look so remote in the far left depiction, but look very unlikely as one moves to the right.
China has had a highly unbalanced sex ratio at birth for years leading to an estimate of 30 to 60 million missing girls. The traditional explanation was male preference, exacerbated by the one-child policy, which led to sex selective abortion and/or infanticide. New research presents evidence that maybe the missing girls were never missing after all.
Researchers may have ‘found’ many of China’s 30 million missing girls

A 2-hour workshop on mapping data from Detroit is offered on Thursday, November 3rd on campus. Perhaps as useful is meeting the presenter who is the founder of Detroitography.com a group that is all about maps and geography of Detroit. And, that also means geographically-referenced data.

Using the TravelTime platform and some simple code, researchers can map how far people can travel in 30 minutes by public transportation from a specific address. This is more realistic than radius circles because these don’t take into account roads, bus routes, etc.
The TravelTime platform includes several countries, including US coasts.
These monthly webinars out of the North Carolina Library Association provide a good introduction introduction to all sorts of data products by subject experts: APIs, mapping, UN data, global trade, court records, etc. Folks can sign up and watch the presentation in real time or as a recording. Slides are available for all presentations.
The U.S. Census Bureau will hold its quarterly 2020 Census Program Management Review on Oct. 28 from 1 to 4 p.m. Agenda topics include high-level program updates, the address canvassing operation and test, 2020 Census content, upcoming tests and 2020 Census systems readiness.
In order to provide wider access to this event and share information about 2020 Census planning with the public, the Census Bureau will broadcast the review live at <www.census.gov/newsroom/census-live.html>. If members of the media would like to attend in person, please contact firstname.lastname@example.org.

Altmetrics are metrics and qualitative data that are complementary to citation-based metrics. Some argue that these metrics should be considered in tenure decisions, along with the more traditional metrics of publishing in a high impact journal with many citations. Almetrics cover a wider range of materials than just those in professional journals – websites, blogs, materials in repositories like figshare or GitHub. It also covers more than citations, such as views and downloads.

This blogpost from the Altmetric site, shows how Altmetrics can be incorporated into a traditional tenure document.
And an even more informative article on Altmetrics is a summary written by Yan Fu in a PSC news report:

How One 19-Year-Old Illinois Man Is Distorting National Polling Averages
New York Times | Nate Cohn @Nate_Cohn

This is a nice illustration of the decisions polls make when they weight their respondents. The authors disagree with the decisions of the USC/LA-Times pollsters, but applaud them for transparency:
It’s worth noting that this analysis is possible only because the poll is extremely and admirably transparent: It has published a data set and the documentation necessary to replicate the survey.
The article has multiple illustrations of what the trend of national Trump support would have been with different weighting decisions. Check it out.
