We would like to randomly split the sample from a panel so that 50% see Q1A and the other 50% see Q1B. so for a sample of 100 panel respondents 50 would answer Q1A and 50 would answer Q1B and then go on to answer all the other questions. So Q2 everybody would answer ie 100 respondents. I am not sure how to set this up.
