PROJECT EXPERIENCE
Paywall A/B Test Analysis
https://drive.google.com/file/d/1DMWd87I5Bo85zJlTuS5MjaDlefTVNpTH/view?usp=sharing
Technologies: Python, Pandas, statsmodels, Seaborn.
General description: Analysis of an A/B test evaluating the impact of a "50% discount"
presentation on a subscription paywall.
Idea: To determine if changing the pricing presentation increases the install-to-payment
conversion rate without changing the actual price.
My tasks: Cleaned and processed test data, calculated conversion rates, performed
statistical significance testing (Z-test for proportions), and built visualizations with
confidence intervals.
Result: Proved the statistical significance of the variant group (+45.9% relative CR increase)
and provided actionable business recommendations for the feature rollout.

cleaned anomalies, and designed an interactive dashboard in Tableau.
