3.4.3 Statistical Analysis
Each category was considered as a variable and the corresponding score was considered as its value. Thus, there were six variables each of which had a particular
value. Chi-square test was performed among the six values i.e. the scores of the six
categories. A significant result (χ
2
= 24.90, df = 5, p < 0.01) was obtained from this
analysis (Table 1). The overall inter linkage among the issues has been depicted in
Fig. 1.
