By the time we reach voting age, almost all Americans have at least a high school education. That means we have been exposed to numerous math courses, and hopefully passed them. But that does not mean we have a good sense of numbers. Innumeracy in the modern sense means that one does not have a good grasp of statistics and probability and how they impact one’s worldview. This article by FiveThirtyEight discusses a recent study of how little the blue and red teams know about each other, a prime example of how innumeracy is causing real problems in America.
It seems that a many intro statistics students struggle with the “language” of stats. I am working on a micro-course on that topic and I ran across this article: Statistics for people in a hurry. It is well worth the read the 8-minute read.
This NYT’s article is another showcasing their excellent use of data visualizations to communicate important concepts. Well worth the 7 minute read.

Over the last five-plus years that I have taught BUS233, I have noticed some characteristics of students who do well in the course. This is anecdotal evidence, for sure, but I think worth considering if you are facing 233 with a bit of trepidation.
Students who make a B or Better…
- Ask a lot of questions.
- Choose a stats technology quickly – usually StatCrunch – and invest the time to learn it.
- Spread their work in the course out over the week – they do not wait until Sunday afternoon to start.
- Make a detailed notebook of how they work problems.
- Learn the language of statistics – how to read word problems looking for keywords and phrases.
- Memorize a few key concepts (not equations) early in the term.
If I had to pick the most important, #1 is #1.
