I'm trying to perform a Friedman test for 3 conditions (nonparametric data). My results have 16 variables with 16 points to score (all of which must be used). Respondents can score 16 points against a single variable or 1 point against all 16 variables. The 3 conditions are past, present and future. However I donít know which type of ranking to use for my Friedman Test (rank, savage score, fractional rank, fractional as a percentage, sum of case weights)
Andy Field (Discovering Statistics) and Julie Pallant (SPSS Survival Manual) donít appear to offer much guidance!
Öany thoughts would be appreciated.
