About this table

Description	Discrete choice experiment: Scottish consumers (online Qualtrics survey recruited via Prolific, quota-representative by gender and age, Feb-Mar 2024; n = 299) chose among two options and a 'Neither' alternative on 6 cards; profiles describe packs of shortbread biscuits varying Bere flour content, nutritional value, quality label, place of purchase, place of production and price per pack (GBP). Outcome is the chosen option (opt-out allowed).

Notes

Conjoint table (irw_conjoint). Discrete choice experiment, 6 cards of Option 1 / Option 2 / Neither from a fixed blocked design (36 cards in 6 sets); choice = selected option (wording not deposited, paraphrase), opt-out yes (Neither chosen on 512 cards; both profiles 0). One respondent answered only 2 cards (kept, as in the deposit). Level text from the codebook's English labels; postcodes dropped.

These notes describe the source data, which the IRW reproduces as released. All notes are listed on the Data Notes page.
