Assessment, Statistics, and Research

  This stunning chart is worth a look by all those who present data at conferences or in classes.  The source of this chart and four more useful charts is an article on inflation by Flowers and Siegel of the Washington Post 10 June 2022. I recommend a look at the other charts as well. An additional comment. Charts about economic issues like the cost of food and energy are also about human behavior. People raise prices and people pay more for what they need or want. Too often we separate the cost of things from what people are doing.

 Congratulations to Team USA for an outstanding performance at Tokyo 2020 in 2021 I enjoy sports. I used to follow player stats as a boy and kept track of my own even though I wasn't much of an athlete. The Olympic medals offer an opportunity to see how different presentations of data make a difference. You could even offer more perspectives if you consider many other countries than the top winners.  ALL MEDALS : The USA easily wins overall. Great Britain beats Japan.

China's population is huge compared to most nations so they don't do so well. You can find countries with smaller populations who did extremely well like Australia. There are of course other factors to consider. Perhaps you thought of some? Wealth. Importance of Sport. The unique problems of COVID-19 infections o...

 FBI Reports Data Active Shooters 2019 FBI Report Several aspects of the FBI reports can help students, faculty, and leaders in presenting important data to the public. 1. On page 3 they define what they mean by an "active shooter." And they clarify that the report does not include all gun-related shootings. 2. Page 4 uses a two-color strategy to compare two years (2019, 2018) side by side. The selection of numbers to compare seems reasonable to understand what is going on. 3. Page 5 tells us where the shootings take place using a color-coded map. It offers a clear look though the selection of green may not be the best color when the gray areas are the "safe zones" where no shootings took place. See photo at the top of this page. 4. The graphics on page 7 offer a helpful illustration of ways to present information to the general public. We see data, graphic comparisons, and clear colors that help differences stand out.
