The Choice Profiles table shows the 12 choice sets, each consisting of two profiles. The Choice Runs table enables you to record the preferred profile in the column Response using the profile ID. Enter 1 if Choise1 is the preferred profile or 2 if Choice 2 is the preferred profile. Alternatively, if the respondent has no preference, leave the response missing.
The Choice script in the Choice Profiles table facilitates analysis of experimental results. It opens a completed launch window for a Choice Model. For information about Choice Models, see Choice Models in the Consumer Research book.
The DOE Dialog script in the Choice Profiles table relaunches the design dialog.
