Best practices in Conjoint testing

  • Though the minimum number of responses required for accurate Conjoint testing is 400, we recommend ordering t least 750 to 1500 completes for more representative data.
  • As you add combinations, and change the number of packages per screen, keep an eye on the message at the bottom of the test that says how many questions the test is using.
  • To help combat respondent fatigue, add some Instruction Text before the Conjoint test to give respondents some context, and let them know what's coming next (e.g. "You will repeat this task 8 times.).
