Why you Should Probably Take Statistics in High School

  Mark Twain once famously said, “There are three kinds of lies: lies, damned lies, and statistics.” Perhaps the sentiment he is implying there wouldn’t be quite so true if probability and statistics were taught to more students.

Statistics is the practice of collecting and analyzing data and using that information to infer proportions in a whole from a representative sample. That practice is quite different from what happens in other kinds of math, but it is no less important. Most American students will touch on statistics early on in school. They might encounter some basic problems like, “if I have ten marbles in a box and six of them are red and four of the blue what is the chance I pull out a blue one?” However, as they get deeper into grade school and into high school they are very likely to skew away from statistical instruction. Indeed, no state currently requires that high school students take a course in statistics but many do require credits in other courses like algebra and geometry. As a result, students are far more likely to encounter geometry and algebra in middle school. 

Geometry is kind of a one-off and many high school students will study it for a year. High School students who do well in math tend to eventually be fast-tracked to Algebra 2 and from there, trigonometry and calculus are natural progressions. Probability and statistics are kind of like the town that gets bypassed by the railroad tracks and not enough students are taking a detour to get there.

The problem with this is that statistics is an extremely practical math. The American Statistical Association lists about 150 broad college majors that are likely to require a college-level course in statistics. Far less require calculus or trigonometry and those that do may well also require statistics. Anyone who might have to read a study or report that speaks to some collection of data will likely benefit from some understanding of statistics and that happens in countless careers that require a college degree. Actually, I might be hard-pressed to think of one career that would never require someone such a report. 

Still, outside of colored marbles in bags, the first time the majority of American students study probability and statistics deeply is at the college level. Encountering a new kind of math for the first time in college does not likely lend itself to the best possible outcome. Even getting into college could be an issue. Here is a stat for you, about 30% of the math questions on the SAT relate to statistics or data analysis.

The good news is that while no high school requires statistics, many do offer it. So, the simple solution to all of this is to take the statistics class your high school offers. You have to take some math anyway and this should count for that. You’ll be better prepared when you likely have to take a statistics class in college and even if you don’t, you’ll be a more well-rounded mathematics student for the rest of your life. Probably.
