Statistical Analysis
SPSS® (Statistical Package for Social Sciences) for
Windows 21.0 is used for statistical analysis of the data. Average and
standard variation for numeric variants; number and percentage for
categorical variants are given as definitive statistics. Chi Square and
Fisher’s Exact test for intergroup comparisons for categorical data is
used. Since the distributions were not normal (Kolmogorov Smirnov
p<0,05) in numerical variations, intergroup comparisons are
done via Mann Whitney U for two groups, Kruskal Wallis H for more than 2
groups are used for statistical analysis. Results are accepted as
statistically significant if p<0,05 in 95% confidence
interval.
