MaxDif
Example of MaxDif

In the above example the respondent is asked to select from a list of features about banks the feature that they would least prefer and the feature that they most prefer when selecting a bank to bank with.
The respondent must select one item on each side of the grid and they are prevented fro selecting the same item on either side by the system.
To set up the question type you need to input the items (above called FEATURE) and the text headings for the left and right columns. The features can be piped in from another question if required and full formatting control is provided for the column headings by using the rich text editor.

Adding the items to the centre column.

There are four ways of entering the items to your Max Dif question.
The first icon allows you to enter an un-formatted text column heading. You can cut and paste the text into these column heading boxes from MS Word without worrying about the Word formatting coming across. The default theme formatting will be applied which is suitable in most cases. This is the method used in th eabove example.
The second option opens the image library. If you wish your items to be images, select the images you wish to use in the grid by clicking on and selecting the appropriate images from the image library. Note that you can upload new images to your library from this option also.
The third option allows you to create a rich text item. Clicking on this icon creates a placeholder - you then click on this placeholder to open the rich text editor and type in and format your column heading.
Clicking this icon will open a pop up text box that will enable you to cut and paste all your column headings from another document in one go. Each column heading must be on a separate line. Any document formatting from the original document will be deleted.
Note the mix of types used to achieve the desired formatting. For greater detail on the three types of answers you can create see Creating a question - General Concepts.
