FAQPage Schema
How do I analyze A/B test results for statistical significance?

Analyze A/B test results by computing primary metric conversion rates, p-values, and confidence intervals for control and variant groups. Provide experiment duration, traffic splits, and guardrails to receive clear statistics and practical ship, extend, or stop recommendations.

What is the best way to decide whether to ship an A/B test variant?

Decide whether to ship an A/B test variant by evaluating statistical significance alongside guardrail metrics. This calculates p-values and confidence intervals to produce practical recommendations on whether to ship, extend, or stop the experiment.

Can I use Python code to calculate p-values and confidence intervals from raw experiment data?

Yes, you can calculate p-values and confidence intervals from raw experiment data by optionally generating Python code. Provide raw data alongside traffic splits and primary metrics to compute statistics and guide product decisions programmatically.

How do conversion rates and guardrails affect my A/B testing decision?

Conversion rates and guardrails affect A/B testing decisions by establishing practical significance and safety thresholds. Analyzing primary metric conversion rates against guardrails ensures statistically significant changes do not negatively impact other critical product areas.

What do I need to run an A/B test analysis for web product features?

To run an A/B test analysis for web product features, you need the experiment's primary metric, duration, traffic splits, and guardrails. Supplying these inputs computes statistics like p-values and generates actionable product recommendations.
