We are implementing partial-profile method. For each tasks there are only 4 Attributes out of 7. But how can we set the fixed task. We have chosen different levels of the same 4 attributes for each concept. And the rest 3 attributes stayed N/A. We had no error sign when we exported, but later we have confronted problem while importing this design.
In order to solve this problem we have changed all N/A to the level "no information shown", which is a blank. Error sign did not show again. However i have concern that this actually showed all the attributes in fixed task. Will it affect the result of the study?
Thank you in advance.
