Dear Deborah, It would do no violence to the data to reverse the order of the nonzero scores. It requires only a linear transformation: revscore = 8 - score if score > 0. Your data, however, are not suitable for ANOVA (and, if they were, you would use two-way ANOVA rather than one-way, and perhaps consider companies as a random factor). The correlation inherent in the rankings is one problem, and the preponderance of zeros is another. I wonder what sort of analysis the people who designed that question had in mind. It's a good idea to plan ahead.
