| with the skill | 0.762 | ± 0.214 | 7 |
| without the skill | 0.544 | ± 0.282 | 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.
