About this table

Description	Candidate conjoint: 311 MTurk respondents each compared up to 6 pairs of hypothetical U.S. presidential candidates varying on 8 attributes (military service, religion, college, profession, income, race/ethnicity, age, gender); forced choice plus a 7-point rating of each candidate.

Notes

Conjoint table (irw_conjoint). Outcomes: choice between two candidates ("which would you prefer for President") and a 1-7 rating of each, recoded from the source's 0-1 scale. The source has no task or profile column, so both are inferred from row order; 122 of 311 respondents have fewer than 6 tasks. No opt-out. MTurk worker IDs dropped.

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

Design

Topic	candidate choice
A profile represents	person
Country	unknown
Language shown	unknown
Language of stored levels	en
Randomization restrictions	unknown
Task order	inferred from row order
Profile position	inferred from row order

Task order or profile position was rebuilt from row order; analyses of position or task order should leave it out.

Outcomes:

choice	Which of these two candidates would you prefer to see as President of the United States? [choice, forced]
rating	On a scale from 1 to 7, where 1 indicates that you would never support this candidate, and 7 indicates that you would always support this candidate, where would you place Candidate 1? (Candidate 2 analogous) [rating, 1 (Never Support) to 7 (Definitely Support)]
