Hi,
I'm designing a new CBC study for one of my real estate client to analyze price sensitivity.
We are only considering 2 competitors + client estate for this, which in actual market account for 30-40% share. We can not go beyond 2 competitors as these 2 are direct competitors and others are small players.
We are assuming that 60-70% people will choose None. We are planning on a sample of 300-500 respondents.
My question is with above sample size and high % of none is it appropriate / robust to estimate price sensitivity.
For eg if we use a 10 cards design, we'll have 5,000 responses for all respondents out of which 3,000 may be none. Will the remaining 2,000 responses give me robust results to draw conclusions.
Should I use an ACBC instead of CBC?
Kindly guide me to get best possible outcome for my study.
Your help is greatly appreciated!!
Thanks & regards,
Raj
