I have a data set of 129 authors with different years of publishing experience and how importantly they consider the factor 'peer-reviewed' while selecting a journal to publish (these answers are ordinal type from 1 to 5 in Likert scale). I am planning to apply Kruskal-Wallis test to determine is there any significant difference between their ratings according to their experience of publishing (experience as the independent variable & rating as the dependent variable). However, the number of responses in each category (each years of experience) are not equal. For example, there are 5 authors with 10 years of experience while there are 2 authors with 6 years of experience. So is it possible to apply KW for this problem?

Your answers will be highly appreciated!
