Not measured
This receipt carries no verdict: it does not record that a model answered the run.
The two arms
| arm | mean | spread across cases | cases |
|---|---|---|---|
| with the skill | 1.000 | no spread recorded | 5 |
| without the skill | 0.474 | no spread recorded | 5 |
No lift is stated for a state that did not measure one. A spread is the sample standard deviation of the per-case means: a descriptive spread with no coverage probability. The verdict above reads each case's two bands, not these aggregates.
