Hotter Summers

As we are wrapping up a record setting two week arctic cold spell across the northern regions of the country, I thought it would be nice to think about warmer times to come.  The article, It’s Not Your Imagination: Summers are Getting Hotter, also includes some nice histograms if you are covering statistics in your … Continue reading


Hurricane Harvey dumped more water in one storm than any previously recorded storm in continental U.S. with 3-4 day totals over 40 inches of rain in multiple areas, and Cedar Bayou registering a record breaking 51.88 inches!  The National Weather Service had to introduce new colors to map the deluge: How to put all this … Continue reading

Canary in the Art Market

Financial literacy is a common component of many QR courses.  Faculty cover basic material on loans and investment, with compound interest providing a great example of exponential growth.  Students tend to come into our classes very un-savvy with respect to financial planning, not really having any idea what a stock or bond is and even … Continue reading

Marathon of Numbers

Great article, Do the Math: Our Problem with Numbers, on being a critical consumer of statistics as “hard facts”.  The Chicago Tribune stated a rough estimate of crowd size at the Chicago marathon as being 1.7 million people.  So what would this look like along a 26.2 mile route?  Would this mean a dense crowd … Continue reading

The Liberal or the City?

Which came first, the city or the liberal?  It is an interesting question.  Looking at the political map from the recent election we see blue (liberal) surrounding cities and quickly turning red (conservative) the farther you travel from downtown. I like this map showing just the areas that voted for Clinton in 2016, basically small … Continue reading

Inequality Not Worse

I thought we should finish out 2016 with some good news, and yes I have to reach back to September for this, but America’s middle class (as in the exact middle i.e. 50th percentile) income of $56, 516 did increase by 5.2% in 2015!  Which definitely deserves a Wooooohooooo!  As this was the first raise … Continue reading

Murder Rates Up! Or just up?

Rhetoric in an election season is of course filled with exaggeration, but it is not just the candidates who engage in hyperbole.  The article, Murder Rates Rose in a Quarter of the Nation’s 100 Largest Cities, uses  FBI crime data to explore whether the real increase in homicides in our nation’s largest cities was indeed … Continue reading

Recurring Flooding

In 2012 the Virginia General Assembly passed a bill to study sea level rise, but only if the phrase “sea level rise” was replaced with “recurrent flooding”.   Four years later, with sea levels still rising, Virginia was happy to accept $100 million from the Federal Government to help safeguard Norfolk, VA from recurrent flooding.  The … Continue reading

Bloomin’ Innumeracy

Each semester I start my class off with a short article on Innumeracy, Why American Consumers Can’t Add.  It’s from 2009 but the information is still relevant today, especially the message the “there is a hidden epidemic in our country, innumeracy, and the consequences are dire.”  I assign a new article each week, and require … Continue reading

Power and Law

The issue of race in our society continues to dominate headlines, and remains a hotly debated topic on many college and university campuses.  I assigned the article, Chicago Police Department Plagues with Systemic Racism, to facilitate this conversation in my class.  As with stereotype threat, it is not enough to ask students whether they feel … Continue reading
