A/B Testing: A Complete Guide | Course Preview

Most teams know A/B testing matters, but few run tests they can actually trust. Vague hypotheses, wrong sample sizes, peeking at results early, and misread outcomes quietly undermine the data and lead to design decisions built on shaky ground.

Join Deborah O'Malley (founder of GuessTheTest), as she gives you an 8-step process for running trustworthy experiments from start to finish. You'll learn to uncover high-value testing opportunities in your analytics and heatmaps, write clear and measurable hypotheses with defined KPIs, set statistically sound sample sizes and durations, avoid the silent mistakes that ruin reliability, and confidently call a test a win, loss, or inconclusive.
