Learn directly from Andrew Mende

Much more before this course A/B testing felt like something “the data people” understood and I was just supposed to nod along to Andrew explains statistical power in a way that doesn’t make you feel dumb, which I really appreciated. Some parts were still heavy, especially sample size, and I definitely had to rewatch a section or two

I joined because our team kept arguing based on opinions, and I wanted a better way to talk about product decisions The course helped me understand when an experiment is actually useful and when it’s just noise dressed up as data. I especially liked the sections on primary metrics and reading results without jumping to conclusions too early

This is not one of those courses where you just watch the videos, feel productive for an hour, and move on. You actually have to think. I took it pretty quickly, and it gave me a much cleaner way to connect experiments to real product goals.  I would’ve liked a few more beginner examples before some of the trickier cases

Loved the product thinking in this course. The course pushes you to slow down and ask, “What are we actually trying to learn here?” That alone changed how I think about experiments. I am already applying the learnings at work, including some tricky experiment lines with multiple variants / low traffic / etc

I had run A/B tests before, but this course made me realize how messy my process actually was. The stuff about hypotheses, metrics, power, and sample size seems obvious in hindsight, but I was skipping pieces of it all the time. Andrew makes the stats feel way less intimidating, especially for someone who isnt trying to become a statistician. Def worth it 👍
