4,920 rated or chosen profiles from 410 respondents, in up to 4 tasks of 3 profiles varying on 5 attributes.
| Description | Supermarket shoppers in Can Tho, Vietnam (Sept 2020; n = 410) made 4 choices each among two certified premium rice options and a status-quo rice, options described by four certification labels (low-emission, eco-friendly, ethically produced, low glycemic index) and price; fixed blocked design. |

| Randomization restrictions | yes (stated by the source): fixed blocked design: 16-profile orthogonal fractional factorial (alternative A) with a shifted alternative B (modular arithmetic, every attribute differs from A), 4 blocks of 4 cards; profile 3 is always the status quo (no certification, VND 20,000/kg), so the status-quo levels occur only on profile 3; within A/B, label and price levels balanced (price 22,000/24,000/28,000/32,000 each 25%) |
| Task order | inferred from row order |
| Profile position | recorded in the deposit |
Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead. Task order or profile position was rebuilt from row order; analyses of position or task order should leave it out.
