Three levels of hierarchy were identified based on the findings of extensive exploration i.e.
Category......composed of Areas And Area are .....further composed of Factors
1. In confirmatory survey, practitioners were asked to rank Categories within themselves (Level 1 rank order). 2. Then they were supposed to rank the Areas within each Category (Level 2 rank order). For example:
Category 1 (has Area11, Area12, Area13,....) Category 2 (has Area21, Area22, Area23,....) And so on....
3.Within each area, factors were asked to be ranked (Level 3 rank order).
For each Area we have Area11 (has Factor111, Factor112, Factor113....) Area12 (has Factor121, Factor122, Factor123....) And so on....
All identified items were theoretically orthogonal and no rank order had more than 7 items. We applied Kendall?s W at every level separately.
Statistically, can it be objectionable? Is there any other rank order test suitable to given scenario?
