From the Advanced Question Types select the Side-by-Side Matrix option
The Matrix Dimension is the different dimensions (Importance, Satisfaction, Expectation etc.) that you want to measure.
The attributes are the different factors that apply to all the dimensions that need to be measured.
The Scale definition is the number of points (and the text for each of the points) you want in the scale.
In cases where there is a possibility that respondents cannot choose a scale or a particular attribute is not applicable to them, they should be able to choose a value in the scale that DOES NOT contribute to the overall score (average.)
At this point, SurveyAnalytics DOES NOT allow for editing the structure of the question. You'll have to delete the question and re-create the question if you want to change the structure. You can however edit the text of the questions and the scales as you see fit.
