the most familiar food was assigned to 1 and continue rank among the list of the foods until the least familiar food.
How to perform weighted ranking or any suitable method can be suggested for data analysis as they are ordinal data.
Hi Carole,
Thank for your help on this matter. I will go to look into it!
You can use the (nonparametric) aligned ranks Friedman test. In R, with the scmamp package. See example in attachment.

In SAS, see the 2nd example in attachment.
By the way, your data seem to be ipsative, i.e. the sum of the rankings, for each participant, is constant. If there are, e.g. 5 foods to be ranked, the sum is 1+2+3+4+5.
Greer & Dunlap have argued one can run ANOVAs on such measures. Just run a repeated measures ANOVA with the Food rankings as repeated measures factor.

Jos Feys Thank for your sharing the syntax files! I prefer to analysis my data in SPSS. Can you explain more on repeated measures ANOVA? Do you meant the ONE-WAY REPEATED MEASURES ANOVA?
