Starting today, I’ll post one technical question each day on this blog. Depending on the question itself, I may post a hint. In the future, I’ll archive old questions on the book’s companion website (http://www.quantcareer.com) along with answers to select questions.
I keep the daily questions and the archive separate, so you get a chance to solve them on your own first. I hope you like this arrangement. (Plus, it’s not easy to update the website, at least not as easy as updating this blog.)
Today’s question is… (drumroll, please)
Sample Question #1 (statistics)
How do you test whether a data sample is normal or not?
[Comment: this tests your knowledge in basic statistics; there are several different methods to test normality.]
