Q1Domain Verified
When designing an A/B test for a new user onboarding flow in a mobile app using Firebase A/B Testing, which of the following is the most critical factor to consider for ensuring statistically significant results?
The sample size required to detect a minimum detectable effect (MDE) with a desired statistical power and significance level.
The duration of the A/B test, aiming for a fixed period like two weeks regardless of user traffic.
The conversion rate of a secondary, non-critical feature within the app.
The total number of users who have ever downloaded the app.
Q2Domain Verified
In the context of Firebase A/B Testing, what is the primary purpose of defining a "conversion event" for an experiment?
To identify and quantify the desired user action that indicates the success of a particular app feature or change.
To monitor the overall app stability and crash rate across different user segments.
To track the total number of app opens during the experiment.
To measure the engagement of users with a specific in-app advertisement.
Q3Domain Verified
A mobile app developer is running an A/B test on a new "Add to Cart" button color. They observe a 5% increase in conversions for Variant B (new color) compared to Variant A (original color). However, the p-value is 0.15. What is the most appropriate interpretation of this result?
The observed difference is likely due to random chance, and there is insufficient evidence to conclude Variant B is better.
The test should be immediately stopped and rerun with a larger sample size.
The observed difference is statistically significant, and Variant B should be implemented.
Variant B is definitively superior to Variant A and should be rolled out.
