which statistic parametric test should I use?

#1
What parametric test should I use for the social research questions on how people were likely to choose from 3 products (1 - less likely, 10 more likely)? i.e., I am conducting a research, where i want to know which supermarket Australian residents prefer. He recruited 10 adults living in australia (between 18 and 65 years old) and asked them to rate how likely they were to choose Woolworths, Coles, ALDI. if given a choice, from 1 = not at all likely to 10 = extremely likely.

If you measured three responses from the same n=10 subjects,
then this is a repeated-measures design. You could use a
repeated-measures analysis of variance. But in regard of the
very small sample size, a "non-parametric" Friedman test
would be more robust.

With kind regards
