Is This Course For You?

Is This Course For You?

This course is for you if you have ever experienced:

The frustration of looking at fluctuating statistics that do not seem to converge.

The distress of not getting statistical significance on a logically promising idea.

The struggle of running experiments when visitor traffic is low.

The anxiety of not knowing when an A/B test winner is genuine or not.

The fatigue of convincing people when you have a finding contrary to popular belief.

This course teaches how to tackle these challenges with an intuitive understanding of randomness.
