Comparing Population Means under Local Differential Privacy: with Significance and Power

Understand

A statistical hypothesis test determines whether a hypothesis should be rejected based on samples from populations.

• In particular, randomized controlled experiments (or A/B testing) that compare population means using, e.g., t-tests, have been widely deployed in technology companies to aid in making data-driven decisions.
• Samples used in these tests are collected from users and may contain sensitive information.
• Both the data collection and the testing process may compromise individuals' privacy.
