[…] The descriptive statistics was reported in the form of mean, standard deviation, confidence interval, median, frequency, and percentages. Distribution of data was checked by Shapiro–Wilk test and Kolmogorov–Smirnov test. Concurrent validity was checked by Pearson correlation Coefficient. Comparisons of correlation coefficients between three groups were done by online available software (http://www.vassarstats.net/rdiff.html). Reliability was measured by Cronbach's alpha coefficients. The comparisons of Cronbach's alpha coefficients between three groups were done by online available software Cocron comparing Cronbach's alphas (http://www.comparingcronbachalphas.org/). Calculation of facility value, discrimination index, and point biserial correlation coefficient was done according to standard formulas.[] Comparison of marks, time, facility index, discrimination index, and Z-transformed point biserial correlation coefficient between three groups was done by one-way ANOVA followed by Tukey's post hoc test. Distracter analysis was conducted according to standard formulas by Microsoft Office Excel 2007.[] Except the specific calculation done by online software mentioned above, other comparisons and analysis were done by SPSS Statistics for Windows, version 17.0., SPSS Inc., Chicago, IL, USA.
