Library · import

Your past winners, recalculated by Probant.

Probant imports each variant’s raw data: visitors (or sessions, named as in the export), conversions, revenue, and its spread when the export includes it. Imported tests join the library, the quality score, and the priors used in readings. They can’t be relaunched, receive no events, and don’t count toward your plan.

Probabilities, p-values, and “significant” labels from the original tool aren’t imported. Probant recalculates the difference and its range, the verdict at the 5% threshold in a single look (the original plan isn’t known), the winner’s curse correction, and the false-positive risk. What the tool reported stays shown alongside, under its name.

What your past A/B tests say

7 announced winners, 3 hold up after recalculation.

Of 12 imported tests, the export shows for each one whether AB Tasty declared it a winner; that announced verdict stays next to the recalculation. Probant rereads each test at a two-sided 5% threshold, in a single look, with the winner’s curse correction.

Announced winners that hold up: 3 of 7; 3 winners in total according to Probant, announced or not.
Average announced gain: +9.5%; Average of announced winners (7), as the tool showed it.
Gain corrected for the winner’s curse: +4.6%; The same tests, pulled toward what the workspace’s tests bring in on average.
Average false-positive risk: 12%; Among winners that hold up, assuming each test was sized for 80% power, the usual convention. With less power, it would be riskier.

The original plan isn’t known. If the tool was checked every day and the test stopped as soon as it looked like a winner, its winners are even more fragile than the recalculation shows.
Traffic split checked on 4 tests with known planned shares: 1 skewed measurement.
Probabilities, p-values, and “significant” labels from the original tool aren’t imported. Every figure here is recalculated from visitors and conversions.
