Predicted sample size for significance level 0.05 and statistical power 0.90 under the assumption of an intraindividual mean difference of δ (with standard deviation s(d)) in laser flare meter values (refers to example 2)
| s(d)=20 | s(d)=30 | s(d)=40 | s(d)=50 | s(d)=60 | |
|---|---|---|---|---|---|
| δ = 40 | 6 | 9 | 13 | 19 | 26 |
| δ = 50 | 4 | 6 | 9 | 13 | 19 |
| δ = 60 | 4 | 5 | 7 | 10 | 13 |
| δ = 70 | 4 | 5 | 6 | 8 | 10 |
