Quiz: What Did You Learn?

In this course, we’ve taken you on a tour of information available on the experiment Results page and discussed ways these details can help shape your optimization journey. In the next courses, we'll look closer at taking action on your results.

Let’s review what you have learned with a short quiz. Select the best response to each question. When you've answered all the questions, select the submit button to check your answers.

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

How are unique conversions useful on the Results page?

• They help you analyze your outliers in conversion activities so you can figure out what caused the anomaly
• 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

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

When viewing the results summary module, what does the Visitors count represent?

• Count of each visit to the site as total visitors
• Count of new visitors bucketed into an experiment for the first time as unique visitors
• You designate this when building the experiment, it can be either unique visitors or total visitors

What is the conversion rate for the winning variation in the above results?

• +12.61
• +5.70
• 45.70%
• 52.61%

What should be considered before resetting your experiment's results?

• The action will immediately clear the experiment results.
• Experiment results will be re-calculated from the this point onwards.
• Only 30-days of raw data will be available for export from the date of request.
• All of the above
• None of the above
