Sample Size for Evaluating Bias
| Half-Width of 95% CI for Bias | |||||
|---|---|---|---|---|---|
| ± 1% | ± 2% | ± 3% | ± 4% | ± 5% | |
| Varb*=5% | 22 | 8 | ≤5 | ≤5 | ≤5 |
| Varb=10% | 42 | 13 | 7 | ≤5 | ≤5 |
| Varb=15% | 61 | 17 | 9 | 7 | ≤5 |
| Varb=20% | 80 | 22 | 12 | 8 | 6 |
| Varb=25% | 99 | 27 | 14 | 9 | 7 |
The between-case variance (described in Table 4) is represented here as the variance divided by the bias.
