One of my earlier blogs on handling percent (%) values in SAS was very popular (it's been viewed over 34,000 times!), so I thought I'd write a similar blog on handling time (mm:ss.ss) values in SAS ... This past weekend I was in a dragonboat race (that's me in the […]

What cities have the most and least profitable public transportation services in the US? Perhaps you can find out in this graphical visualization of the data! The US data I'm analyzing here covers things like buses, vans, and rail ... but it might be even more interesting to analyze data from […]

A recent study by Bai & Anderson has found that some hospitals charge 10x (ie, 1000%) higher than the standard rates set by Medicare. Many news agencies have posted the list of the 50 US hospitals that have the highest markup. But I am more visually oriented, so of course I used SAS […]

Have you ever been bitten by a mosquito? What are the odds it carried the West Nile virus? ... Perhaps a lot higher than you thought! Here's a picture of a mosquito that kept 'bugging' me around my computer desk at home - good riddance, I say! The West Nile […]

My previous blog was about popular first names ... now for a blog about popular surnames (ie, last/family names)! But before we get started, here's a little pop-quiz - what country is my friend Mr. Foley's surname from? I recently saw the following interesting map on dadaviz.com. It shows the most […]

A couple of years ago, I blogged about the most popular baby names in the US over the past 100 years. This time, I focus on the most recent year, and take it to the state level! But before we get started, here's a picture of my friend Jennifer's daughter, […]

I guess most of us have a morbid curiosity about how we're going to die ... which is probably why Francis Boscoe's Causes of Death map went viral (no pun intended, of course!). This blog post shows how to create such a map... But first, to lighten up the mood a bit […]

I saw an interesting graph on dadaviz.com that claimed Italians had gone from drinking twice as much as Americans in 1970, to less than Americans in recent years. The data analyst in me just had to "independently verify" this factoid ... But before I get into the technical part of this […]

Mount St. Helens volcano here in the US had a big eruption 35 years ago this week! Do you know exactly where it is located? Perhaps this SAS map can help... As you might have guessed, I'm a big fan of the awesome power of nature (hurricanes, tornadoes, lightning, earthquakes, and […]
