Bayesian statistics

look at those statistics and make a judgment about how they can relate or how they play into that statistic. What intrigues me is who comes up with those statistics? That is why I choose the career statistician to research about. Most people think having a career in statistics would be mind-numbing because you have to use math. This in most cases, math can be unexciting or dull. The reason using math for statistics can be enjoyable is quite interesting. I believe that statistics can relate to…

The purpose of this study is to evaluate the impact of interventions designed to reduce hospital admissions or length of stay amongst frail older people. Databases that were used to retrieve the studies are: PubMed / Medline, PsycINFO, CINAHL, BioMed Central, Kings Fund library. Studies were limited to publications from period 2007- present. Researchers classified interventions into those which aimed to prevent admission, interventions in hospital, and those which aimed to support early…

2. There is a good, positive correlation between the six variables in the HC scale. The Cronbach Alpha is .769. From looking at the Inter-Item Correlation if I delete any variable the Cronbach Alpha will go down so there is no need to delete anything. The SE scale Cronbach Alpha was .686, after looking at the Inter-item Correlation chart all of the variables were positive but there were a few variable that were low. If I was to delete any variable the Cronbach Alpha would decrease. So the…

Joseph performance on the attention tasks during this testing exhibited variability. Joseph’s performance on visual attention task was below the threshold of statistical significance; however, it did demonstrate subtle difficulties in the area of detectability, inattention, response speed consistency. He also made slightly more anticipatory errors than others in his age group. There was slight reduction of speed noted during the later blocks. His response speed also showed slight decrease when…

lot on how statistics is involved in our everyday life. We also have learned why statistic is useful in comparing things. In our book Naked Statistics by Charles Wheelan we read some chapters in where we use stats in three different ways to get close to the answer without using all the data. We see how indepednt variables and dependent variables relate to each other and how we can get close to seeing how close they relate without using the full data. Correlation is a form of statistics in…

Bullfrog Dissection Background The American bullfrog, Lithobates catesbeianus, is an amphibian about the size of a teacup.(National Geographic, “American Bullfrog”). This dissection explored the anatomy of a bullfrog that had been pithed. Pithing is a technique used to prevent the frog from experiencing any cruel or unusual pain during the dissection. A pithed frog has had its nervous tissue in its brain severed thus allowing it to maintain normal bodily function during the dissection without…

The VCE mathematics topic that I have chosen is Probability, in Mathematical Methods Unit 1 Area Study 4: Probability and Statistics (VCAA, 2015). The first section presents a literature review of student learning probability. It also addresses the common pitfalls that may impede their learning. The second section outlines a unit plan for teaching probability based on the new VCE study design. Sample activities worksheets and assessment tasks are included in the appendices. Literature Review:…

Analysis: Initially after I received my results from the GMI survey I was surprised by their outcome. Being a Global Studies major, I thought that my overall averages would have been significantly higher than they were. However, after reading through the aspects of each individual section, and a close inspection of myself in regards to the requirements to those sections I began to understand the reasoning behind my scores. When I first started assessing my GMI results, I expected my scores to…

Describe the research question for this experiment. The research question for this experiment is which vaccine is more effective for preventing getting the flu: the shot or nasal spray. What were the null and alternative hypotheses? Null Hypothesis: The shot is more effective than the nasal spray. Alternative Hypothesis: The shot is not as effective as the nasal spray. Were the results of this test statistically significant? .08>.05 Which means the results are not significant. The hypothesis…
