1 Design your own CJ experiment

Guidelines:

1. Relevant and interesting RQ in your discipline [see exercise first lab]
   • Literature is relevant
   • Use previous knowledge and avoid ‘shooting in the dark’
   • However, it can be exploratory
2. Justifiable design choices
3. Pay attention to external and internal validity
4. [if you want to pre-test it, it should be in English and focus on the US so that we can collect responses from Reddit (/r/samplesize) or a HIT platform]

Guidelines:

2. Basic design choices:
   • Attributes (realism vs. theory testing)
   • Levels
     
   • Framing/priming [if RQ requires so]
3. Other design choices:
   • Uniform or non-uniform distribution?
   • Restrictions on combination of certain attributes/levels (please include if necessary)
   • Attribute order constrains?
   • How many profiles per choice-sets? (usually 2 unless specific needs)
   • How many tasks/sample size?
