The two arms
| arm | mean | spread across cases | cases |
|---|---|---|---|
| with the skill | 0.802 | ± 0.052 | 7 |
| without the skill | 0.721 | ± 0.143 | 7 |
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.
