Dear Sawtooth Community,
I have a study including two CBC exercises. Respondents are randomly assigned to either do CBC 1 or CBC 2. Each CBC exercise consists of 12 random choice tasks and 3 fixed tasks. 131 respondents answered CBC 1 and 130 respondents answered CBC 2.
I did run Count Analysis on both CBC´s separately to get a first impression of the collected data. I followed the default CBC Count settings and only included the 12 random choice tasks per analysis respectively, leaving out the fixed ones. The counts output for CBC 1 correctly indicated, that 131 people answered this CBC exercise. However, the first line “Choice tasks included” says that 24 Random and 3 Fixed Tasks were included in calculations. Shouldn´t it be just 12 Random Choice Tasks? In my opinion the additional 12 random choice tasks and the additional 3 fixed choice tasks must stem from CBC 2.
Can somebody please explain to me, why the description of “choice tasks included” (24 Random, 3 Fixed) seems to also include the choice tasks from CBC 2, when CBC 1 is selected for analysis (while the number of respondents, 131, is correct for CBC 1)? How can I make sure that actually only CBC 1 is analysed?
Thanks for your help!
