Topics Distribution of the sample mean. Central Limit Theorem. Confidence intervals for a population mean. Confidence intervals for a population proportion. Sample size for a given confidence level and margin of error (proportions). Poll articles. Hypotheses tests for a mean, and differences in means (independent and paired samples). Sample size and power of a test. Type I and Type II errors. You will be given a table of normal probabilities. You may wish to be familiar with the follow formulae and their application.

I will be applying descriptive statistics to visually display data and calculate measures of central tendency and dispersion to effectively pin point patterns of injury, what medications we give, and what topics to educate our Soldiers to prevent illness and injury. As this course comes to an end I have reflected on the course outcomes and determined that I have successfully achieved the intended learning objectives in the five Modules. I have demonstrated the ability to describe statistics, determine sources and users of Health Statistics. I have been able to identify and demonstrate the importance of the Central Limit Theorem to the study of Health Statistics. As mentioned in my reflective discussion posting I took special interest in the ability to demonstrate the ability to compute descriptive statistics in order to describe the characteristics of a data set as well as applying elementary probability theory to health sciences data. I also mentioned earlier that the ability to conduct parametric and nonparametric inferential statistical tests: t-tests, chi-square analyses proved to be the most difficult for me to learn. Overall this course was very useful for me and will improve the way I run my medical company here in Kuwait. I believe our work here will improve the quality of care through statistical review of our standard operating procedures and protocols in the aid station. I appreciate the learning opportunity this course offered and the feedback

1. Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants scored between (–53.68, 64.64), where did 95% of the values for weight relative to the ideal lie? Round your answer to two decimal places.

Data used in this study is from a previously prepared collection for a different study and hence does not require any instruments. Use of Microsoft Excel and graphpad, an online software, helped in calculating the results and analyzing the data.

Measurement performance in clinical epidemiology is described based on accuracy, reliability, range, responsiveness, and interpretability. The effectiveness of data from a study is based on performance of measurement. Thus, the data from clinical epidemiology must be accurate and reliable to achieve its goal. Validity implies that data measured has to correspond to the true value being measured. On the other hand, reliability ensures that the data recorded can be reproduced (Fletcher et al., 2012). Effective performance of measurements should not contain data

The total number of the study sample was 269 adults. The following criteria were used for selecting the study sample:

all participants were women. The mean age was 34.95 years (SD = 6.8). The mean of nursing experiences was 12.14

Studies for this review were collected using databases such as Google Scholar, Science Direct, and BioMEd Central. Peer Reviewed literature was examined from 2005 to 2015. A total of forty-five studies were examined with ten being used for this review. Cross-Sectional studies and reviews of longitudinal studies were used. Data was collected using primary sources that are first hand observational. Data was collected from questionnaires, interviews, assessment waves, surveys, and focus groups. Most studies were cross-sectional studies (Garcia (2014), Morleo (2013), Lui (2014), Nash (2005), Barnow (2002). Reviews of longitudinal studies were also examined (Jester (2014), Visser (2012), Humskey (2010). A longitudinal study was examined (Degenhardt

Abstract. The abstract well represents the article by first giving a brief and clear background of the research problem where it also includes the population. It then continues to provide a precise overview of the study by summarizing the main features such as the objectives, design, setting, measurements used, results, and the conclusion. In addition, other aspects such as limitations to the research and primary funding sources are cited.

Comparisons among the groups were performed with the use of Pearson's chi-square test, Fisher's exact test, an analysis of variance test, or a logistic regression, as appropriate.

Between July 2002 and December 2009, a group of consultant physicians, statisticians, and professors from Germany, Switzerland, and Austria conducted a study on behalf of CAPNETZ,

The limitations of this study may be limited to inaccuracies, because all responses were self-reported. A recommendation for further studies could collect data directly from the patients chart. Obtaining information directly from a patient’s chart eliminates the subjective data, and makes the information obtain more reliable and
