From ancient clay pots to 100 modern statistical models, explore how we navigate the complex tools used to verify truth and quality in data.

In research software, you’re often writing code to find an answer that literally no one on Earth knows yet. How do you test for a result that hasn't been discovered?

Lena: You know, Miles, I was just thinking about how we use the word "test" for everything—from checking the temperature of bath water with your wrist to launching a missile. It’s one of those words that’s so common we almost forget how much weight it carries!
Miles: It really is everywhere. I mean, did you know the word actually comes from the Latin "testum," which was an earthen pot used for metallurgical testing? We’ve gone from clay pots to complex statistical models. Speaking of which, there’s a resource by Gopal Kanji that covers a staggering 100 different statistical tests.
Lena: 100? That sounds like a lot to keep track of, especially when you're just trying to figure out if your data actually means something.
Miles: Exactly, and that’s the challenge. Whether it’s an "acid test" for character or a "litmus test" for chemistry, the goal is always to find the truth or verify quality. So, let’s dive into how we can navigate this massive world of testing without getting lost in the jargon.
