My client has asked for a multi-select CBC (can select more than one product per task).
This isnt something I have done before - previously always limiting myself to one choice per task and using share of preference to guide multi-choices.
So a couple of questions;
- Can I do this, and how would I analyse the results?
- Is there any issue with asking the question in this way e.g. does it decrease my capacity to predict choice as we split the information available across two DVs?
Thanks for your help,
