I have a problem that I could not solve neither with spss nor with R.
Please, excuse me if it is atrivial question but I did not find any
I have the followig practical problem: we a product that has A, B, C
effects (we differentiated about 30) on health and we want to know
whether these effects are associated with its physical properties
(shape, size, color). We listed all these 30 effects that were
important for us and the subjects received a list of photos in which
the product was indicated in different size and color etc. There were
20 possiblities. The subjects had to order one of these photos to each
effect in the list.
If I make a chi-square test it says only that there is a significant
effect. I also want to know which property or properties caused this
significant effect in the deviation from expected frequency.
I would appreciate your help.
