Medical statistics

unspeakable, experiments were being performed on prisoners without their knowledge or their consent. These experiments were performed against the prisoners’ will and ignored any and all medical conscience that today’s doctors hold as the standard. Though these experiments are considered one of the darkest times in terms of medical-ethics, these very experiments yielded some valuable information. With this in mind, a topic that has arisen decades after the original experiments, is the…

1. Lipira AB, Gordon S, Darvann TA, Hermann NV, Van Pelt AE, Naidoo SD, et al. Helmet versus active repositioning for plagiocephaly: a three-dimensional analysis. Pediatrics. 2010;126(4):e936-45. Researchers in this study analyzed the two most common treatments for deformational plagiocephaly (DP) to determine if there was significant difference in the outcomes of patients using each treatment. Both active repositioning and cranial remolding are widely believed to be similar in efficacy and…

3. PROBLEM & RESEARCH SETTING 3.1 Problem Statement Numerous research studies have been conducted by the CII and also other FEP researchers with regards to the implementation and critical importance of front end planning in project success. But there are very few studies that provide quantifiable statistical data supporting FEP adoption. CII has published data analysis for FEP data which analyses the relationship between project PDRI scores and scope definition, and project cost, schedule and…

Autocorrelation is not expected to be an issue with the model, given that the it is not using time series data, and it can therefore be assumed that there is no autocorrelation present in the model. To make sure that there is no perfect collinearity present in the model, it is recommended to run a collinearity test of the model (see: Exhibit 1.1). If a variable generate a VIF (Variance Inflation Factors) value above 10.0, the model might have a collinearity problem and attempts to correct the…

Introduction Strength is an abstract parameter that consists of many variables that can potentially influence the amount of force being exerted with certain individuals. In another word, strength represents the ability of extortion or endurance. Grip strength is subject to many health concerns and body mass index are few of the factors that could potentially influence the strength of individuals. And that throughout many studies gender and age correlation with grip strength could range from…

Amgis, a flavors and food additives company has a sudden surge in production due to increase in sales and transfer of production from an affiliate. The company requires additional labor to cope with the sudden increase in production. However, strict labor laws have limited the company to hire permanent employees, and overtime employees and forced them to engage temporary labor to keep the process flowing. The company then had to make arrangements with a third party labor provider and the…

Nate Silver’s introduction to The Signal and the Noise offers up an intuitive definition of the split between prediction and forecast. Prediction is judgemental and accounts for future changes and opinions, whereas forecast is pure scientific fact and interpretation of the past events. Neither are anywhere close to perfectly predicting any scenario, but there are times where one produces a mostly accurate estimation of the future. Each strategy has its strengths and weaknesses, which Silver…

Three 3X3” plant pots labelled as A, B, and C were used during our experiment. Each pot contained standard soil media with basic nutrients, and 3 Arabidopsis seeds. All pots were watered with appropriate Hoagland’s Solution formulation three times per week over the next 4 weeks. Pot A (phosphate limitation group) was given a phosphate reduced Hoagland’s solution, whereas Pot B (nitrogen limitation group) was watered with nitrate reduced Hoagland’s solution. Pot C (control) is the control plant…

Literature Review Ⅰ. HOTSPOT MAPPING Hotspot can be defined as aggregations of raw crime data that identify geographic locations of highest incident concentration (Ratcliffe and McCullagh, 1999; Chainey and Ratcliffe, 2005). Hotspots have been formally recognized in the literature as early as 1751 when Henry Fielding suggested focusing on areas of high crime to deter offenders. A notable example of policing with hotspot is the study by Sherman et al., (1989), which found that over 50.4% of all…
