As the Stats Engine collects data, what happens to the confidence interval?

  • The interval narrows
  • The interval expands
  • The interval stays the same - it’s set by you when you set up the experiment

When are unique conversions useful?

  • They help you track when users click a link or share an article from your website
  • They help you control for outliers and track conversions such as selecting the “add to cart” button
  • They can track when users take an unexpected action away from the page and tell you where they went
  • They help you analyze your outliers in conversion activities so you can figure out what caused the anomaly

What is the most significant way that segmentation can help you analyze results?

  • It will automatically turn on the winning variation to the winning segments once the experiment is over
  • It can give you insight into whether or not your results are truly worth implementing
  • It can show you whether a particular segment performed worse than the others to help you decide how to implement results

How can you compare your results to a variation that isn’t the original?

  • You shouldn’t compare results to anything but the original, so there’s no way to do this in Optimizely
  • Use the Baseline dropdown to select a different variation as the baseline
  • The graph readout shows the results for each variation. This is the quickest and most efficient way to compare the variations to one another.
  • Export your results and review them against one another to compare your variations
