Can the AI change my actual test settings in my testing tool?

No. The AI only reads the data you provide to perform calculations. It cannot modify your experiments or settings.

Does the AI decide which version to roll out to my customers?

No. The AI provides a recommendation based on math, but you make the final business decision.

What kind of data do I need to provide?

You need to provide the number of conversions and the total number of visitors for both the control and the variant groups.

Can the AI run the actual A/B test for me?

No. This MCP is for analyzing data that has already been collected. It does not have the ability to launch or manage live experiments.

Will the AI tell me if my sample size is too small?

Yes. Part of the analysis includes checking if the volume of data is sufficient to produce a reliable result.

How to analyze conversion rate significance with your AI

Stop guessing if your test winner is actually a winner. Your AI handles the math to separate real trends from random noise.

Ask AI about this page

Short answer

Is my A/B test result statistically significant?

Your AI calculates p-values and confidence intervals to tell you if your conversion lift is real. You'll get a clear verdict on whether to trust the data or keep running the test. This breakdown shows you how the math works.

The results you get

What your analysis produces

Once you provide your test data, your AI delivers these specific outcomes.

STATISTICAL

Confidence level check

The AI calculates the probability that your observed lift isn't just a fluke. You get a percentage that tells you how much to trust the result.

DECISION

Rollout recommendation

The AI interprets the math to suggest whether you should implement the change or stick with the control. It removes the guesswork from the final call.

DATA

Error margin analysis

You get a breakdown of the margin of error for both groups. This shows you the range of possible conversion rates you can actually expect.

HUMAN

Strategic review

The AI flags if the sample size is too small to be reliable. You then decide if the business risk is worth the current level of certainty.

The workflow

What your AI does when the data arrives.

The AI takes your raw numbers and runs them through a statistical engine.

Ingest test metrics
Your AI reads the conversion counts and total visitors for both your control and variant groups.

Analyze this A/B test: Control had 50 conversions out of 1000 visitors, and Variant had 75 conversions out of 1050 visitors.
Check the significance of this test from my Google Sheet: Control 2% conversion, Variant 3.5% conversion, both with 5000 visitors.
Is this test result significant? Control: 120/2000, Variant: 150/2000.
Run a significance check on these numbers from my Optimizely dashboard: Control 5.2% rate, Variant 6.1% rate, 1200 users each.
