Work smarter – not larger

When you were in Statistics 101, and the Professor said ok, we are now going to learn about the Central Limit Theorem, did you tune out? Did you sarcastically say when is someone going to grab me and order me to tell them about the Central Limit Theorem? Come on, admit it, you did.  Well, so did I – I was 18 years old, and couldn’t care less.

Well, you know what? Understanding the Central Limit Theorem has really big implications for big data analytics. Check out this 20 minute video, and you’ll see that by applying the Central Limit Theorem and some statistical theory, you can approximate the results of an expensive multi-server implementation for interrogating really large databases.

I’ll show you how you can obtain very precise estimates on really large databases by simply applying some basic statistics you should have learned Freshman year (but you were too busy partying, weren’t you?)

stay tuned, I’ll be coming out with a big data analytics class in the New Year.  If you want to learn more about SQL, programming, open source GIS, or Manifold, check out courses at
