A/B testinin en iyi seçenek olmadığı durumlar

A/B testleri her duruma uyan tek bir çözüm değildir. Kurumun için değer yaratmak amacıyla A/B testinin gücünden ne zaman yararlanacağını bilmek önemli olduğu kadar, bunu yapmanın kaynak ve zaman israfı olacağı durumları da fark etmek aynı derecede kritiktir.

İyi A/B testi kullanım senaryoları hakkında öğrendiklerini kullanarak, aşağıdaki senaryolardan hangisi A/B testine uygun değildir?

Exercise 3: A/B testinin adımları Exercise 4: Rastgeleleştirmenin etkileri Exercise 5: Neden deney yapıyoruz?Exercise 6: Korelasyon görselleştirme Exercise 7: Korelasyon mu nedensellik mi?Exercise 8: Metrik tasarımı ve tahmini Exercise 9: Ortalamalar ve oranlar Exercise 10: Reklam gösterimi metrikleri

In Chapter 2, you’ll cover the experiment design process. Starting with learning how to formulate strong A/B testing hypotheses, you’ll also cover statistical concepts such as power, error rates, and minimum detectable effects. You’ll finish the chapter by learning to estimate the appropriate sample size needed to yield conclusive results and tackle scenarios with multiple comparisons.

Exercise 1: Hypothesis formulation and distributions Exercise 2: Strong hypothesis formulation Exercise 3: Plotting distributions Exercise 4: Central limit theorem for means Exercise 5: Experimental design: setting up testing parameters Exercise 6: Interpreting p-values Exercise 7: Error rates in the wild Exercise 8: Experimental design: power analysis Exercise 9: Plotting power curves Exercise 10: Sample size for means Exercise 11: Sample size for proportions Exercise 12: Multiple comparisons tests Exercise 13: Is a multiple comparisons correction needed?Exercise 14: Corrected p-values

Here, you’ll discover a concrete workflow for cleaning, preprocessing, and exploring AB testing data, as well as learn the necessary sanity checks we need to follow to ensure valid results. You’ll explore a detailed explanation and example of analyzing difference in proportions A/B tests.

In the final chapter, you’ll develop frameworks for analyzing differences in means and leveraging non-parametric tests when several assumptions aren't met. You’ll also learn how to apply the Delta method when analyzing ratio metrics and discover the best practices and some advanced topics to continue the A/B testing mastery journey.
