Thus, the researchers concluded that environmental factors were part of the overall equation, determined by comparing the amount of phthalates in those girls who live close to urban areas with factories that manufacture products containing phthalates. One other finding drawn from this sample group was that the levels of phthalates "were significantly higher than the average levels" determined by the CDC (Lee, 2009, Internet). With the second group of four

statistical analyses used. List the statistical procedures used to describe the sample. Power analysis was used in order to discover power of effect. The power was set to 0.8 with a significant level of 0.05. Differences between the intervention and the control group were tested with Pearson's Chi. A t-test was used for the other perimeters. ANCOVA was used for testing changes between the two groups over time. Was the level of

When leaders in the field of criminal justice are going to develop, change or implement policies within their field, it is always important that these developments, changes and implementations are grounded in evidence. Evidence-based practice is universally recognized as essential to good decision making (Noe, Hollenbeck, Gerhart & Wright, 2003). In order to use the evidence, one has to obtain the evidence—and that happens by way of statistical analysis and

In other words, p values correspond to statistical significance, while NNT corresponds to clinical significance. In clinical trials, statistical validity reflects the theoretical basis of the study, with hypotheses being formulated and quantified in terms of likelihood. Clinical significance is concerned with the practical outcome of trials, and with the results of actual treatment and how this relates to the hypotheses that are proven or void. 2. In nursing practice, both

professional fields that confirm, through studies and other means, the effective use of evidence-based practices. The field of education, business, technology, and especially the medical field all, to varying degrees, use the concept of evidence-based practices to improve the manner in which solutions to problems are sought and implemented. It is important that studies are conducted that allow for quantitative and qualitative methodologies to confirm that the practices being

Public Administration The Role of Management Information System in Decision Making in Public Administration (Case Study on Hungarian Central Statistical Office) Organizations require appropriate information in the form of proper databases and reports which plays a pivotal role in decision making. The quality of data holds significant importance as the top management of large organizations derives its high level decisions mostly from the available data rather than inspecting the in depth core
