  • You have now collected enough data to be 99% certain that this conclusion is valid.
  • Recommendation: adopt $variant variant. adopt $control variant.
  • You have collected enough data to be 95% sure that this difference is not simply due to chance factors.
  • Recommendation: let the test run for longer to be completely certain.
  • You don't have enough data to be sure yet that this difference is due to the variant you are testing or purely chance factors.
  • Recommendation: let the test run to collect more data.
