In light of the plot, the researcher thought that the experimental factors should have been Time, Energy and Flux material. Under this scheme, levels (L,L) and (H,H) for Time and Temperature would be Level 1 for Energy (inappropriate energy level) and levels (L,H) and (H,L) for Time and Temperature would be Level 2 for Energy (appropriate energy level). The data would be recoded as:
Factor settings | Response (Breaking strength) |
(L,1,A) | 174 |
(H,2,A) | 77 |
(L,2,A) | 54 |
(H,1,A) | 172 |
(L,1,B) | 158 |
(H,2,B) | 34 |
(L,2,B) | 56 |
(H,1,B) | 137 |
