Statistical Analysis
Data were collected and entered into the software of Statistical Package
for Social Science (SPSS) 20. Numbers and percentage values were given
to show descriptive qualitative data while mean scores, standard
deviations, ranges, and medians with interquartile ranges (IQR) were
given to show descriptive quantitative data. Chi-square test was used to
compare the groups related to qualitative data, while the two groups
were compared in terms of quantitative data and parametric distribution
by using independent t-test and in terms of the nonparametric
distribution by using the Mann–Whitney test. The value of
P<0.05 was considered statistically significant.
