Results for your A/B tests can be found under the Test Resultstab under Insights.
When you get to this page, you'll see a number of columns. The data in those columns represent a variety of different things:
 Page
 This is the page where the test was performed
 Test
 The name of the test that was by the user who created it
 Status
 Has one of two values:
 Active: The test is still running
 Ended: The test is finished or was stopped
 Started
 The date the test began (yyyymmdd)
 Ended
 The date the test finished or was stopped (yyyymmdd)
 Confidence
 The percentage confidence that the winning variant is correct.
 Variants

To understand the data in this column you need to first understand what is represented here. Put shortly, this column gives an indepth look at the performances of both 'versions' of the component you're testing.
In the below example, the line highlighted in yellow is the Variant (the 'changed version' of the component you're testing), and the line highlighted in Purple is the Control (the 'original version' of the component you're testing).
Below are the definitions of some additional metrics mentioned in that column:
 Uniques
 How many unique views each variant has recieved
 Conversions
 How many times the defined goal was completed for each variant.
 Conversion Rate
 The number of unique users divided by the total number of conversions for that variant. This may be a range if data volatility is high for your test.
 Winner

The winner of the test who was either manually chosen when the test was ended by a user, or was automatically determined when either the Variant or the Control reached a confidence percentage that exceeded the predefined Result Certainty of the test.
How do we calculate A/B test results?
We use the Pearson ChiSquared test for calculation of A/B test results. The pvalue is the inverse of the confidence in the results. E.g. a pvalue of 0.05 means 95% confidence (i.e. 1 out of 20 such tests would yield a false positive). You can set the target pvalue lower if you want more stringent test results, although .05 is generally considered acceptable in the world of marketing for all but the largest scale tests.
You'll sometimes see ranges listed for Conversion Rate because of how the ChiSquared test actually works.
In other words, if there were 10 clicks and 100 unique visitors, then that is obviously a conversion rate of 10%. However, the ChiSquared test result would imply that based on the amount of data collected, the implied volatility is still high, and therefore shows a range since expecting a final result in the range of (as an example) 5.0% to 10.0% is reasonable.
ChiSquared test results will not yield a winner until the ranges on both segments narrow with more data so as not to produce an overlap between them exceeding the target pvalue.
