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.
