Episode 53 of Conversion Rate Optimization with Fexingo dives into a common but overlooked A/B testing pitfall: pre-registration bias. Lucas and Luna explain why logging your hypotheses, sample sizes, and success metrics before running a test can prevent p-hacking and false positives. They walk through a real example from a B2B SaaS company that halved its false-positive rate by adopting a public pre-registration log, and discuss how tools like GitHub or simple spreadsheets can enforce discipline. The hosts also share a practical framework for writing a pre-registration entry in under 10 minutes. No more 'I knew it all along'—this episode gives listeners a concrete tactic to make their A/B tests more trustworthy. #PreRegistrationLog #ABTesting #CRO #PValue #PValueHacking #StatisticalSignificance #Frequentist #Bayesian #HypothesisTesting #DataIntegrity #ConversionOptimization #SaaS #MarketingAnalytics #Experimentation #FexingoBusiness #BusinessPodcast #Marketing #CROStrategy Keep every episode free: buymeacoffee.com/fexingo
