Rank Order Questions

[David Lim]

Hi

I have asked 100 subjects to rank two softdrink
products based on their preference. (1 = most
preferred). Ties is not allowed.

Can i use Wilcoxon signed rank test to analyze the
result?

thanks
david

Hi David

Is the ranking binary (1=most preferred; 2=less preferred)?

In that case, use McNemar test, not Wilcoxon.
