I have a dataset using a four point likert scale. I'm using Wilcoxon's signed ranks test for significance between repeated measures. I'm intending to use Spearman's Rho for correlation.
My problem is that some questions had reversed scoring.
i.e. 'Everyone is nice to me' never=0, sometimes=1, usually=2, always=3
'People are horrible to me" never=0, sometimes=1, usually=2, always=3
Some of the reversed questions are part of subsets which are then also compared.
My question is should I convert the negatively scored items i.e. 3-(score), so 0 becomes 3. so I can compare like with like? I'm inclined to do this partly because I can't see how subsets can otherwise be compared.
Is this valid?
