Course Description

The premise of this course is quite simple.

I asked myself: What is the most practical data science technique?

What do I use in the real-world most often?

Methods like neural networks and recommender systems are pretty application-specific, but statistical inference can be used for nearly everything.

  • Website owners: which web page design leads to the highest engagement or revenue?
  • Copywriters: which sales copy leads to the highest conversion rate?
  • Online advertising platforms: which ads lead to the highest click-through rate?
  • Clinical researchers and drug testers: which treatments, drugs, or therapies work best?
  • Machine learning engineers and data scientists: which models have the best performance?


This course has 3 main parts:

  • Maximum likelihood estimation review
  • Confidence intervals
  • Hypothesis testing


Each section prepares you for the next section, to yield maximum understanding and intuition.
