About Statology

Hey there. My name is Zach Bobbitt. I have a Masters of Science degree in Applied Statistics and I’ve worked on machine learning algorithms for professional businesses in both healthcare and retail.

I’m passionate about statistics, machine learning, and data visualization and I created Statology to be a resource for both students and teachers alike. 

My goal with this site is to help you learn statistics through using simple terms, plenty of real-world examples, and helpful illustrations.

You can find me on LinkedIn here.
