I'm trying to run a Discrete Choice Conjoint Analysis for a financial insurance product. When coming up with the cards for the experiment design how do you avoid combinations that are clearly "better"?
For instance if your attributes are
Benefit Amount - (\$1000, \$2000, \$3000)
Benefit Period - (10, 20, 30)
Price - (\$5, \$10, \$20)
You could potentially get a combination of
\$1000, 10, \$20
\$3000, 10, \$5
which seems like a no brainer to select the second option. Should I be trying to avoid this, and if so, how?
