Dear experts,

I have 5 attributes with 3 or 2 attribute levels. The total of 18 or 24 choice sets are both OK for my design. But I chose the 24 choice set. And I made the 24 choice set into blocks. I am wondering if I made something wrong. Should I make 18 choice set with 3 blocks? In the ngene manual, there are requirements for the lowest number of choice sets. Then what is the requirement for the bigger choice sets? I mean the total number of all choice sets in all blocks. Does my design OK, 24 choice sets with 4 blocks?

Many thanks

24 rows with 4 blocks is fine. You can always use a larger design with more blocks without any issues.
