  1. The mean percentage of each group = \(\frac{{{\text{The}}\;{\text{sum}}\;{\text{of}}\;{\text{hand}}\;{\text{hygiene}}\;{\text{percentage}}\;{\text{in}}\;{\text{the}}\;{\text{group}}}}{{{\text{Total}}\;{\text{number}}\;{\text{of}}\;{\text{participants}}\;{\text{of}}\;{\text{the}}\;{\text{group}}}}\)
  2. The Wilcoxon test was used
