SQL is surprisingly easy to teach to young people. Give them a simple table with info that's relevant to them, and help them discover how to filter and aggregate. I think that is more valuable for people to understand and have in hand than statistics; its a gateway drug to analytical thinking.

And frustratingly difficult to teach adult software developers. Speaking from experience trying to teach the devs what they are doing is NOT good practice.
