Some question types have additional commands that alter and enhance their default behavior.

 
Shelf Test: [shelf {...}, {...}...]

If you need to override default item placement in the Shelf Test, you can use [shelf {...}, {...}...] to organize products by shelves. Each argument is a shelf, and its constituents are item indices which go into that shelf. So, [shelf {1,2,3}, {2,3,4}] will place product items 1, 2, 3 on the first shelf and product items 2, 3, 4 to the second shelf.

There are also the following variations of the logic command: [shelf-left ...], [shelf-right ...], [shelf-flex ...], [shelf-center ...]. They specify the required alignment of the items.
Command [shelf-center ...] will have the same result as [shelf ...].

 

Examples:

  • [shelf {1,2,3}, {2,3,4}] - will place product items 1, 2, 3 on the first shelf and product items 2, 3, 4 to the second shelf. Center alignment is presumed.
  • [shelf-left {1,2,3} if q1a1] - will place product items 1, 2, 3 at the left side of the first shelf if a respondent chooses q1a1.
  • [shelf-right {1,2,3}, {2,3,4}] - will place product items 1, 2, 3 at the right side of the first shelf and product items 2, 3, 4 at the right side of the second shelf.

Exclusive Logic

Using Exclusive logic, you can prohibit respondents from selecting certain answer options together in a Checkbox or Multichoice Progressive Matrix question. Exclusive all will prohibit a respondent from selecting any other answer option with the one they have selected, similar to the N/A feature.

 

1. Exclusive

In an answer option text field, enter exclusive logic, using the reference for the answer option(s) you would like to prevent from being selected simultaneously. This ensures a single respondent does not give conflicting answers to this question. In this example, respondents who select Q1A1 (Oil-free) cannot also select Q1A2 (Oil-based). Respondents who select Q1A2 (Oil-based), cannot also select A1 (oil-free), A3 (Water-based), or A4 (Gel-based). While it is not absolutely necessary to add this logic, this ensures a single respondent does not give conflicting answers to this question.

2. Exclusive All

Exclusive all bars respondents from selecting any other answers in addition to the selected answer. In this example, if a respondent selects A8, they will not be able to select any other option. Additionally, we may choose to add a follow up question that uses logic [show if Q1A8]

3. Exclusive in Progressive Matrix Questions

Please note that when programming Exclusive logic into Multi-choice Progressive Matrix questions, the logic must be entered into the Matrix Answer Option field(s). The logic will only trigger if the answer field it is typed into is chosen by the respondent.

In this example, if a respondent chooses SQ1A1, they will not be able to also select SQ1A3.
