This full factorial can be reduced to four full factorials or to four fractional factorials
Thirsty and Purchasing One CAN
Thirsty and Purchasing a 12 pack of CANs
Not Thirsty and Purchasing One CAN
Not Thirsty and Purchasing a 12 pack of CANs
Create a matrix in which you compared every alternative to all of the other alternatives, once.
In terms of the reduced full factorial you need to create two questionnaires by listing all of the possible attribute combinations (one when the product is being sold for $.25/50 per can and one when the product is being sold for $2.00/$4.00 per 12 pack.
Show the trade-offs among the following techniques for measuring preferences
1) full-factorial paired-comparison,
2) fractional-factorial paired comparison, and
3) questionnaires asking for degree of liking of listed items
