Summary & Conclusion: The data obtained after the training were compared with their respective base-line. To see whether base-line data are normally distributed or not, skewness test was done. To check the homogeneity and equal variance one way ANOVA test was done. Pre-post analysis within groups was done using the Wilcoxon signed ranks test. To compare between groups ANOVA was done. Gender analysis was done using Mann-Whitney test. Since the data were not normally distributed and are not of equal variance Wilcoxon signed ranks test was chosen for within group comparison. Between groups comparisons were done using the ANOVA test.
Pre-data were found to be not normally distributed and are not of equal variance. Wilcoxon signed ranks test analysis shows that there was significant improvement in the total creativity scores of the CR group (p=0.016, 10.37%), IQ group (p=0.091, 05.77%) except PS group (p=0.463, 0.77%).
Several factors could have contributed to the increase in creativity scores. The anxiety-reducing effects of yoga practice, which are already known, 4 could have also facilitated this. It was shown that meditation facilitates right hemisphere functioning.5 Yoga leads to relaxation, reduction of anxiety, improved efficiency as given in earlier references. Yoga as an intervention has the components of stimulation and relaxation. It induces a deep psychological stability, harmony and calm state of mind.7 This may be the reason for the positive effect of the three yoga modules in improving creativity as assessed in terms of Fluency, Flexibility, Originality and Elaboration.
Mann-Whitney test was done to compare the pre-training value of boys and girls. Results suggest that, there was a significant difference between base line-data of boys and girls on the one component-fluency and there were no significant difference for the other three components i.e. flexibility, originality and elaboration. Comparison between total pre-values of boys and girls showed no significant difference between boys and girls at base line.
But Wilcoxon signed ranks test showed that boys and girls in fluency component are improving significantly. Therefore, no major gender factor is shows in this study.
This study shows significant improvement in creativity in all groups except PS group.
