Dağılımların dengesi

A/B testlerimizde rastgeleleştirme yanlılığını hızlıca kontrol etmenin başka bir yolu da, farklı varyantlar arasında değişmemesi gereken metrik ve özniteliklerin dağılımlarının ne kadar dengeli ya da dengesiz olduğuna bakmaktır. Örneğin belirli cihazlar, tarayıcılar veya işletim sistemlerinin yüzdelerindeki büyük farklar — örneklemlerimizin yeterince büyük olduğunu varsayarsak — dahili kurulumumuzda daha büyük sorunların belirtisi olabilir. Senin için yüklenen AdSmart ve checkout veri kümelerini incele ve öznitelik dağılımlarını kullanarak iç geçerliliği kontrol et. Hangi veri kümesi daha geçerli bir iç kuruluşa sahip görünüyor?

In this chapter, you’ll learn the foundations of A/B testing. You’ll explore clear steps and use cases, learn the reasons and value of designing and running A/B tests, and discover the most commonly used metrics design and estimation frameworks.

Exercise 1: What is A/B testing?Exercise 2: When an A/B test is not best Exercise 3: A/B testing steps Exercise 4: Randomization effects Exercise 5: Why run experiments?Exercise 6: Correlation visualization Exercise 7: Correlation or causation?Exercise 8: Metrics design and estimation Exercise 9: Means and proportions Exercise 10: Ad impressions metrics

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.

Exercise 1: Veri temizleme ve keşifsel analiz Exercise 2: Oranlar EDA Exercise 3: A/B test verisi temizleme Exercise 4: Sağlamlık kontrolleri: İç geçerlilik Exercise 5: SRM Exercise 6: Dağılımların dengesi

Exercise 7: Sağduyu kontrolleri: dış geçerlilik Exercise 8: Yenilik etkilerini tespit etme Exercise 9: Simpson paradoksu iş başında Exercise 10: Oran farkı A/B testlerini analiz etme Exercise 11: Oran farkı A/B testi Exercise 12: Güven aralıklarının yorumlanması Exercise 13: Oranlar için güven aralıkları

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.

Exercise 1: Analyzing difference in means A/B tests Exercise 2: T-test for difference in means Exercise 3: Pairwise t-tests Exercise 4: Non-parametric statistical tests Exercise 5: Parametric or non-parametric?Exercise 6: Mann-Whitney U test Exercise 7: Chi-square test for independence Exercise 8: Ratio metrics and the delta method Exercise 9: Delta or not?Exercise 10: Delta method Exercise 11: A/B Testing best practices and advanced topics intro Exercise 12: Best practices Exercise 13: Day-of-the-week effect Exercise 14: Wrap-up: A/B testing in python
