Hi all,

Yes, there are a total of 81 participants in my study, and 9 subjects in 9 cells. I collected the data online, first by asking their weight and height (to obtain their BMI), then they were asked to randomly click one of the links to either picture-viewing condition. Using the example I made earlier, 3 conditions (C1, C2, C3) and 3 BMI groups (G1, G2, G3), suppose C1 already has 9 subjects from G1, the remaining subjects from G1 will be assigned to C2 or C3 randomly.

I'm not sure if I can still call it random assignment, as I made sure the numbers of each cell were about 9 subjects, with similar no. of subjects from each BMI classification in every condition.

Sorry I didn't provide clear enough information about assignment of subjects, thank you all for your help.
