31,284 rated or chosen profiles from 869 respondents, in up to 12 tasks of 3 profiles varying on 4 attributes.
| Description | German online respondents (November 2024, n = 869) made 12 purchase choices among 3 packages of cherry tomatoes (or none) varying packaging material (bioplastic or conventional), biodegradability, extra shelf life and packaging price, after random assignment to an information text about bioplastics or none. |

| Randomization restrictions | yes (stated by the source): fixed fractional design: 12 cards (of 36 combinations) in 12 choice sets of 3, identical for all respondents; each level appears equally often |

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.
