Similarly,
in the case of non-FA farm workers, education status differences also
affected the mean rank of the response (H = 18.02, P = 0.001).
Responses from non-FA workers with no education had a higher mean
rank (more frequent pesticide use) than those with elementary education,
grade 9 education or higher education, although pairwise comparisons
of these mean ranks again failed to identify specific significant
differences between the cohorts
