Fisher exact test and Pearson Chi-square test were performed to examine the statistical difference for the participant's demographic factors and awareness between site general managers and OHS managers. For reference, the Pearson Chi-square test is generally conducted for the comparison between the groups of categorical variables, but when the sample number is small (i.e., when the frequency in the cell is small), the Pearson Chi-square test could lead to incorrect result. In that case, the Fisher exact test was carried out.
