How Data Scientists Use Bayesian A-B Testing in Marketing

What this episode covers

Lucas and Luna dive into Bayesian A/B testing—why it's replacing frequentist methods for marketing experiments. They walk through a real case from a mid-size e-commerce company that used Bayesian inference to compare email subject lines, reaching a decision in half the time with clearer probability statements. The episode covers the core difference: instead of a p-value, you get a direct probability that version A beats version B. They explain how priors work, the role of Monte Carlo simulation, and a concrete example where a company saved thousands by avoiding a false negative. By the end, you'll understand why more data teams are adopting Bayesian methods for faster, more intuitive decision-making—and how to explain it to stakeholders without the math. #BayesianA/BTesting #DataScience #MachineLearning #MarketingAnalytics #Experimentation #ABTesting #BayesianInference #MonteCarlo #Priors #PosteriorProbability #Ecommerce #EmailMarketing #StatisticalMethods #DataDrivenMarketing #ConversionRate #Frequentist #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
