Table 4E: Significance of normal distribution
Since the results from the K-S test are not below the critical value of d 0,95 =0.349, we
can assume that the sample is taken from a normally distributed statistical population
(with a significance level of α = 0.05).
Difference in mean values
For a clear demonstration of the effectiveness of the treatment, I will illustrate the
differences in mean values from the various different observation periods by
comparing the observation period reference week (RW) with the observation periods
after the treatments (PT1W, PT2W, PT3W). (see table 4F)
Difference Z (RDQ) Z (VAS)
RW-PT1W 1.297 1.358
RW-PT2W 2.200* 2.502**
RW-PT3W 2.759** 2.869**
*significant (α=0.05) **very significant (α=0.01)
Table 4F: Test statistic Z (dependent variables)
After the first therapy session, the results show no significant changes. After the
second therapy session, however, we can observe a significant change in the
dependent variable quality of life (RDQ) and a very significant change in the
dependent variable pain (VAS). After the third therapy session, test results even
show very significant results for both dependent variables (VAS, RDQ).
