Z –Test: a statistical test used for inference (inference – is the act or process of deriving logical conclusions from evidence‚ statements‚ ideas‚ etc. known or assumed to be true) which determines if the difference between a sample mean and the population mean is large enough to be statistically significant‚ that is‚ if it is unlikely to have occurred by chance. The Z – test is used primarily with its standardized testing to determine if the test scores of a particular sample of test takers are

STUDY FINDINGS Before comparing the group means‚ assumptions for the paired sample t-test were evaluated and no violations were noted. Results from the paired sample t-test revealed statistically significant differences (p <= .05) in student competency self-assessment between the pretest and the posttest‚ and the posttest and the retrospective test on all 19 competencies (Table 2). Cohen’s effect size values ranging from 0.51 to 2.30 suggested moderate or high practical significance. These findings

and the post test mean depression score for the experimental group is 13.36. This shows that the mean for depression in this group decreased. According to the statement that empowerment techniques have an important role in self management of ESRD‚ decreasing of the depression mean after the test would be highly important or a positive impact on depression although this is not a significant amount of decrease. 4.
