| Data structure | Type of test | Power | |
|---|---|---|---|
| If cell is responsive to an odor | Fitted data, non-normal | Kolmogorov–Smirnov test | p < 0.005 |
| ROC analysis CI | Fitted data, normal | t test | p = 0.63 |
| ROC analysis CT | Fitted data, normal | t test | p = 0.08 |
| ROC analysis +/–ΔCt | Fitted data, normal | t test | p < 0.001 |
| Spike count contrast enhancement for +/–ΔCt | Fitted data, non-normal | Wilcoxon signed-rank test | p = 7.57e-5 for +ΔCt responsesp = 8.64e-5 for –ΔCt responses |
| Spike count contrast enhancement for CT | Fitted data, non-normal | Wilcoxon signed-rank test | p = 0.20 |
| Spike count contrast enhancement for CI | Fitted data, non-normal | Wilcoxon signed-rank test | p = 0.18 |
| Peak amplitude contrast enhancement for +/–ΔCt | Fitted data, non-normal | Wilcoxon signed-rank test | p = 2.41e-6 for +ΔCt responsesp = 2.08e-8 for –ΔCt responses |
| Peak amplitude contrast enhancement for CT | Fitted data, non-normal | Wilcoxon signed-rank test | p = 0.97 |
| Peak amplitude contrast enhancement for CI | Fitted data, non-normal | Wilcoxon signed-rank test | p = 0.21 |
| ΔCt sensitivity is step magnitude dependent | Normal distribution | t test | 1.25-fold change: p = 0.72;1.5-fold change: p < 0.01;2-fold change: p < 0.01 |
| ΔCt sensitivity is step duration independent | Normal distribution | Wilcoxon test | For spike count p = 0.08;for peak amplitude p = 0.12 |
