Excel. The statistical analyses, using SPSS 20.0, were based on the
relative proportions in each region. Chi-square tests (p b 0.05) were
used to compare the differences between the two regions. We used
Kruskal–Wallis tests for quantitative variables with nonhomogeneous
variances or nonnormal distributions and analyses of variance for quantitative
variables with normal distributions and homogeneous
variances. A canonical correspondence analysis using Canoco 5 was
selected to determine the relationship between the backgrounds of
the interviewees and their levels of awareness of the dangers of pesticides
to the environment and human health.
