Hello,
in my experiment I have two group of different cultures, each group is made of female and male (gender) and each participants can give correct and incorrect response, to the stimuli which are black/n/white or coloured. I tryed to perfom a 3-way anova with the fit model Y=response time (continuos variable) and X I did a full cross with culture, gender and colour; I also nest subjects with gender. In some of the effects the outcome shows Lost DFs, what this could be due to?
Thank you:)
