The researchers were trying to establish whether electro puncture treatment (EA) coupled with exercises coupled would have an effect on the levels of pain, functional improvement and disability. The researcher wanted to have this information since the effectiveness of therapeutic intervention in treating low back pain hasn’t been convincingly demonstrated (Yeung, Mason, & Leung, 2009). In light of this, the researcher attempted to establish whether acupuncture would be combined along with Western medical management techniques so as to alleviate the pain and disability that is associated with chronic low back pain. …show more content…
As a statistical tool, the t-test was necessary for this research based on several grounds. The first reason for use of the t-test was that it is used to compare the calculated means of two groups of samples that are statistically different from each other (Cox, 2006). The researchers therefore adopted this test since it could enable them to compare the means of the 26 participants in the exercise group to that of the other 26 participants in the exercise plus EA group. In addition, this research required that post test studies had to be conducted after doing immediate tests at the hospital. These tests were done to the participants after one and three months. With this requirement, the t-test was necessary in order to establish the level of statistical significance between the two means (Hughes, 2011). In this research, the t-test was used to determine whether there was a statistical significance between the means of the groups and establish the actual degree of
