Part 5 PAT2 Pilot (let me know when you reach this part)

Go back to this discussion board and take each group member’s survey. (let me know when you reach this part)

You may give truthful or non-truth answers when you take their survey. This round is only a pilot, so statistics will not be computed.

As you take their survey, focus on methods of best practice and reducing bias.

Make sure the survey has:

  • a title,
  • a brief introduction that includes relevant contact details, intent of survey, anonymity,
  • and any relevant instructions
  • a ‘thank you for participating’ after you submit your answers,
  • you are not required to sign in to the survey (emails are not collected)
  • survey questions are not required to be answered

In the last survey question (which should ask for feedback), provide feedback on the above, AND on any or all of the following:

  • Sensitive topics and the optional responses
  • Question order – “priming”
  • Response order
  • Asking to recall facts
  • Limited responses
  • Leading questions
  • Anchoring questions
  • Word connotation
  • Double barrel questions
  • Double negative questions
  • Uninformed questions
  • Ambiguous questions
