Statistical analysis two independent sample tests compare the mean of the randomised case-control group. To find the significant difference between the two groups, data collections are mean value, so t test is the suitable test to compare the mean value of the two groups in normal distributed data (Menz, 2004). Result of the t test shows body mass index significant p value .005 less than .05 and the mean value of the BMI in case group greater than control group. The null hypothesis rejected, there is a significant difference in the two groups in body mass index.
Foot posture index shows p value .004 less than .05 and again the mean value of FPI in case group higher than the control group. In this case also null hypotheses are rejected and show the significant difference between two groups. Two independent sample t tests shows greater significant difference, it states that two group as difference in the body mass and foot mass index. This supports the hypotheses being tested by the researcher. Participants with chronic plantar heel pain case group should differ from the control group in obesity and pronated foot to support that, these two factors may be the risk factor for chronic plantar heel pain.
Standing heel raise test shows p value .050 greater than .05 the null hypothesis is accepted and there is no significant difference between the two groups regarding this test and shows the negativity of the hypothesis being tested .Standing heel test indicates the endurance of the calf muscle, the test result shows that there is no difference in the calf muscle strength between the two groups. Researches as taken data based on the limb affected more by pain but in the outcome meas...

...te the foot is pronated. Author justifies that pronated foot will increase the dorsiflexion.Thereis no linear relation found between the ankle dorsiflexion and the chronic heel pain. This correlates the foot posture and the dorsiflexion range of motion, but in the chi-square test it shows the independence of the two variables. Previous study as found the association between the ankle dorsiflexion and strain on the plantar fascia, author determines research requires finding association of the increase in translation of the tibia straining the plantar fascia.
Randomised case control study cannot be taken as a causation, authors explains that accuracy in the case analyse was low as more variables could be included. Authors suggest further research to determine the other hypothesed causative factors for case accuracy. Author had no competing interest.

- Discussion of the Statistical Analysis From a large cohort of mid-high SES women who were screened for antenatal depression, a statistically significant association was found between the interactions of elevated depression by short cervix and the outcomes of PTB and LBW. The same association was not found for the outcome of SGA. Depression alone was significant in the initial main effects models for PTB and LBW, but the introduction of interaction terms reduced the effect. The change was less substantial for LBW, where odds ratios and their respective 95% confidence intervals were only marginally insignificant.... [tags: Pregnancy, Childbirth, Obstetrics, Statistics]

- Statistical significance seeking (i.e., p-hacking) is a serious problem for the validity of research, especially if it occurs frequently. Head et al. provided evidence for widespread p-hacking throughout the sciences, which would indicate that the validity of science is in doubt. Previous substantive concerns about their selection of p-values indicated they were too liberal in selecting all reported p-values, which would result in including results that would not be interesting to have been p-hacked....

- The study based on Shortness of Breath with Daily Activities (SOBDA): validation and responder thresholds in patients with chronic obstructive pulmonary disease (Watkins, Wilcox et al. 2013) indicate that they selected 365 patients after excluding non-eligible criteria for their randomized treatment strategies. Sample size calculation was performed by considering 0.90 power, two sided significance level 0.05 and effect size 0.5 (difference between responders and non responders) based on the evaluation results (standard deviation) of the responsiveness of the SOBDA questionnaire....

- 5. Conclusions and Discussion Our survey results indicate that the good pace of AMT adoption in India continues with slight increase in pace in a comparable way. The grand average of adoption for all the 25 technology in 2010 is 2.125 (1-not implemented, 2-implementation in progress, 3-fully implemented) which was 2.002 in 2001. With respect to future plans for adoption the average for all technologies is 1.954 currently which was 1.867 (1-no plans, 2-considering plans, 3-have plans) in 2001. Similarly, the 2010 and 2001 values respectively for plans requiring investment are 0.505 and 0.620 (0-no, 1-yes).... [tags: Research Analysis]

- Discussion Board Selecting a Quantitative Study Design After reading the Creswell chapters, and the supplemental texts I was able to develop a research topic that could be explored through multiple research designs. Originally, I proposed the use of a correlation study in order to identify the “direction and degree of association” between retention rates of first year teachers and job satisfaction (Creswell, 2012, P. 354). I clearly outlined my independent and dependent variables, collection process, and study limitations.... [tags: Scientific method, Research]

What are the differences between descriptive and inferential statistics. Descriptive stats summarize data so the data can be comprehended. The researchers prepare a frequency distribution which shows the frequencies as descriptive statistics. Percentages, and averages are also descriptive statistics. Therefore, the descriptive statistics describe sets of data collected through observation.... [tags: Statistical significance, Statistics]

The introductory section of this research emphasizes common types of injuries a collegiate baseball player may experience. Since it mainly focuses on the function of overhead-throwing motion, the emphasis on concentric internal rotator strength was utilized to decrease the upper extremity plyometric program. Additionally, it is stated in the introduction that if the shoulders external rotator musculature is not strong enough, the athlete is more susceptible to shoulder injury....

- Right-side (post) Descriptive statistics are presented in Table 1. An independent one-way ANOVA exposed that there were not significant difference between the means, F(2,12) = 0.539, p=0.273. This symbolized a small effect size; η2 =0.082, revealing that 8.2% of the variation in visual acuity performance was credited for by the varying time usage of digital device. The Post hoc comparisons utilizing Tukey HSD in table 4 corroborated that there was no difference in visual acuity of the individuals with varying periods of time spent on digital devices....

- Data collection and measurement Operational and conceptual definitions are an important part of research. An operational definition is what the researchers have to measure the concept and collect the needed information. Conceptual is the abstract meaning of a concept. In the article, the operational definition is the Likert-type scale that was used. The conceptual is the beliefs and knowledge of the neonatal nurses in kangaroo care. After reading the article, it appears that there are several key variables.... [tags: Scientific method, Statistical hypothesis testing]
