Statistical significance

In order to discuss the differences between clinical and statistical significance, it is important to understand what each means separately. According to Polit & Beck, statistical significance refers to "the results from an analysis of sample data are unlikely to have been caused by chance, at a specific level of probability" (2018). On the other hand, Polit & Beck define clinical significance as “the practical importance of research results in terms of whether they have genuine, palpable effects on the daily lives of patients or on the care decisions made on their behalf" (2018). Statistical significance mainly has to do with data and numbers. This is because there are values within research which can support the objectives and be used as…

relaxation; receptive music therapy has correlations with the reduction of blood pressure, muscular tension, and perceived pain. It has relations with the stabilization of heart rate, endorphin levels, and brain waves, as well as improvement towards immune systems and body movements (Lepke-Sims). PLOS ONE, a peer reviewed scientific journal by the Public Library of Science, has further reveal the significant physiological effects of receptive music therapy; it dramatically reduces stress in…

‘Time’ represents EMG T2-T1 values. The rows directly below this represent the 2 different exercise sessions (1= Pre-CHO, 2= Post-CHO). For each exercise session, the standard deviations are shown, the sample size (i.e., N), and the significance. Each of the participants (N=9) performed both tests. The asterisk in the foot note provides criteria for significance (Sig<.05). The column ‘Sig’, determines whether or not the difference between the mean times were significant. According to the…

14.5 software package. Correlations were carried out using the Spearman rho in order to detect any possible correlations between demographic information and item ratings. The Mann-Whitney U test was utilized to compare statistics amongst the subgroups based on graft type, surgery, age, and time post-surgery. Significance was set at p < .05. The authors…

Similarly, mean RIs were significantly raised in POAG patients as compared to PACG patients. While in CRA, mean PSV was significantly lower in PACG patients as compared to POAG patients. The difference in rest of the parameters did not reach up to the level of statistical significance. Optic nerve head is mainly supplied by the short posterior ciliary arteries which is a branch of ophthalmic artery. The contributions from central retinal artery and pial vessels are very small. [29] Moreover, the…

average) and to observe any significant differences between the individual respondent groups (“Always”, “Usually,” or “Sometimes” or “Never”). The ANOVA will also allow for the p–value, Mean and the Standard Deviation of each composite topic. Furthermore, a Tukey’s significance test was performed after the ANOVA on four of the composite topics (Nurse communication, Doctor communication, Medicine instructions, and Home care information) to further compare the significance of the groups, and to…

hand hygiene techniques: they recommend decontaminating with alcohol-based hand rub and spread evenly over all areas of the hands until dry, when washing with recommended soap and water wet the hands first with warm water (not hot water because overtime can cause irritation) and then apply soap and rub vigorously for at least 15 seconds and rinse and dry with disposable towel (Boyce & Pittet, 2002). This experiment follows the scientific method because it requires the process of doing…

of radicle length within lentil bean seeds was affected by the environmental aqueous solutions, which was made up of either a table sugar, dextrose or a control. It presented that there was not a statistical difference between the table sugar or dextrose aqueous solutions in comparison to the radicle lengths since the P values were less than 0.05. Although, there was a statistical increase in radicle length with the comparison to the control. If these seeds were able to reach the average seed…

provided by the repatriates responding by mail versus those who were interviewed by phone and no statistical differences were found (Eschbach, Parker, and Stoeberl 275). The respondents surveyed represented a cross section of industries, education levels, experience levels, jobs held, age, marital status, sex, number of children, and cultural difficulty. The questions asked focused on general adjustment, interactional adjustment, job adjustment, effectiveness, communications, self-maintenance,…

standard deviation of (1.57). Test of Hypothesis There was a significant difference in the mean number of days that the signs were displayed at the p<.05. Population 1 is statistically significant with Population 2 and Population 4, but not with Population 3. Population 2 vs Population 3 and Population 4 were insignificant. Lastly, Population 3 vs Population 4 were also insignificant. Discussion People who live in high political interest neighborhoods will leave their winning…
