Table I shows the analysed data on Survical Pain
The pre-test means of Survical Pain were 24.38 for Yogasana group,
24.70 for Pranayama group and 24.72 for Control group. As the obtained F-ratio
1.538 was lesser than the table F-ratio 3.04, the pre test was insignificant at 0.05
level of confidence for the degrees of freedom 2 and 297.
The post-test means were 15.75 for Yogasana group, 17.75 for
Pranayama group and 24.42 for control group. As the obtained F-ratio 902.998
was greater than the table F-ratio 3.04, the post-test was significant at 0.05

level of confidence for the degrees of freedom 2 and 297.
The adjusted post-test means were 15.76 for Yogasana group, 17.42 for
Pranayama group and 24.41 for Control group. As the obtained F-ratio 897.258
was greater than the table F-ratio 3.04, the post-test was significant at 0.05 level
of confidence for the degrees of freedom 2 and 296.
Scheffe’s post hoc test was therefore resorted to find out the
significance of ordered adjusted final mean differences among the groups
Table I (A).
The Table I (A) shows the Scheffe’s post-hoc test results. The ordered
adjusted final mean differences for Survical Pain of experimental groups I, II
and III were tested for significance against Scheffe’s post – hoc F-ratio.
