I am doing a pricing conjoint, where I have 2 attributes: SKU and price.
I will be taking 7 existing client SKU's and 13 existing competitor SKU's in account.
The client also wants to test new SKU's. They have 9 new SKU's they want to test.
I am a bit afraid that the total number of client SKU's (7+9) in the design will bias my outcome?
Any thoughts?
