Number of blocks in main survey
Posted: Mon Oct 19, 2020 7:27 pm
Dear all,
I'm about to start my main survey with a sample size of 600-700 participants that I hope to reach. My question is, would it provide enough variation for this sample size if I create 24 choice sets in total as three blocks consist of 8 choice sets? is there any criteria for this issue? Some papers in literature apply more for ex. 80 choice sets in 10 blocks.
