Variance
Variance is how much a result moves around when you repeat the same test.
In a little more detail
AI search has a lot of it: the same question asked three times can give three different answers. Any tool that checks once is reporting variance and calling it a result.

- Sampling: Sampling means asking the same question several times instead of once, because AI search does not give an identical answer every time.
- Confidence interval: A confidence interval is the range a measured number is probably within, given how many times you measured.
