“When is Santa’s birthday?”

March

This depends on who you think Santa is. Let’s look at our top Santa contenders from yesterday.

So there you have it. Two unknowns, one unknowable, and two votes for the middle of March.

Now if you’ll excuse me while I make some quick calculations on my computer….

proc means p1 p25 p50 p75 p99 data=santafile;
class region;
var age_year;
weight gravitas;
run;

Looks like Santa’s birthday is most likely March 15, with a 95% confidence interval of 3.16 (year 0) – 3.14 (year +1).

About Shala Howell

I spent two decades helping companies like Bell Labs, Juniper Networks, and a genetic testing company that was later acquired by CVS translate some of the world’s most complicated concepts into actionable, understandable English. Now I'm working on a much harder problem -- fostering children’s curiosity and engagement in the scientific, artistic, and linguistic world that surrounds them. The first book in my Caterpickles Parenting Series, What’s That, Mom?, focuses on how to use public art to nurture children’s curiosity in the world around them. My next book, Did Dinosaurs Have Belly Buttons?, is currently planned for release in 2018. In the meantime, you can find me blogging about life with a very curious Ten-Year-Old at Caterpickles.com, chatting about books and the writing life at BostonWriters.blog, and tweeting about books, writing, science, & things that make me smile at @shalahowell.
