Comparison of VAS Results at Rest and During Breath for Three Groups

Introduction.
The aim of this research study was to investigate the comparison between VAS results at rest and
during breath for three groups; 1, 2 and 3. To make such comparisons, descriptive statistics and
independent samples t tests were employed.
We tried to answer the research question on whether there existed differences in VAS results at
rest and during breath among the three groups under study.
The hypothesis that guided our study was;
H 0 :Thereis no difference∈VAS results at rest ∧duringbreath amongthe three groups .
H 1:There is difference ∈VAS results at rest ∧during breath among thethree groups .

Descriptive statistics
Comparison between VAS score means at Q 15 min
The figure below shows the comparison between VAS score means at rest and during breath for
groups 1, 2 and 3 for Q 15 minutes. The results show that group 2 has the highest means for VAS
at rest and during breath, followed by group 1 then group 3.
Comparison between VAS score means at Q 30 min
The results in the figure show that group 2 has the highest means for VAS at rest and during
breath, followed by group 1 then group 3.
