Fractional Factorial Designs: A Tutorial
- Matches
Factorial gives the source's answers. Where they differ, this page says why: some are misprints in the source.
Examples
Each example, and how closely Factorial gives its answers.
- A 2^2 experiment in X1 and X2: main effects and the interactionExampleMatches
- A 2^3 experiment in X1, X2 and X3: the main effect of X1ExampleMatches
- The number of runs of a two-level full factorial in 1 to 10 factorsMatches
- The regular half fraction of the 2^3, with X3 = X1X2Matches
- Five factors in 16 runs: the half fraction with X5 on the highest-order interactionMatches
- Six factors in 16 runs with X5 = X2X3X4 and X6 = X1X2X3X4: resolution IIIMatches
- Six factors in 16 runs with X5 = X1X2X3 and X6 = X2X3X4: resolution IVMisprint found
- Six factors at resolution V need 32 runsMatches
- Project 1: a 2^(7-2) screening design of seven intervention components (12 of its 32 runs printed)Matches
Misprints
Misprints found in the source, by page. Each shows what the source prints and what its own data give.
Aliases: 1p. 43
Book 2346Data 12346, 235, 456
1 times 2346 or 1456 is 12346, not 2346: the slide writes the word of the defining relation

Book 1456Data 12456, 135, 346
2 times 2346 or 1456 is 12456, not 1456: the slide writes the word of the defining relation
