ending last year. The population for this study was selected for under the conditions that the doctor writes at least 1,000 prescriptions in Medicare Part D under the premise that brand-name drug use would have a major effect on Medicare as a payer this leads to a large sample size as Medicare takes care of 39 million people in the country. However, there contentions against these sampling conditions, in the article Dr. David W. Parke II state that payments from pharmaceutical companies do not…

of a hypothesis or demonstrating a known fact. Then there is an observational study in which is when there is trying to undertake the knowledge of knowing a cause-and-effect relationship. The best thing for each of these kind of data collections would be how important randomization techniques are, because each test needs a sample size of a population…

for this study will be undergraduate college students in introductory criminology and criminal justice classes at John Jay College of Criminal Justice in New York, NY. Based on preliminary power analyses, a minimum sample size of 159 will be necessary to detect a medium-sized effect (f = .25) with a power of .80 at an α level of .05. The participants will be randomly assigned using a computer based algorithm to watch one of three brief videos which depict a police traffic stop resulting from a…

(Chamberlain, 2016). Using this method, researchers should develop a comprehensive list that is not structured (Chamberlain, 2016). Once the list has been compiled, the researcher should choose a random spot on that list, based off of the total sample size, and then select by interval moving forward (Chamberlain, 2016). While drawing a random sample is ideal, it is not always feasible. Therefore, another alternative sampling approach, which is considered less desirable, is referred to as the…

that HAI increases mood, a one way ANOVA was calculated. As displayed in table 1, the effects of conditions had no significant difference on mood in people, F (2, 42) = 1.5, p = 0.23. To test the effect of species, a 2 (species) x 3 (condition) factorial ANOVA was calculated on mood state, stress rating and happiness rating. For mood state there was no main effect for species, F (1, 42) = 0.2, p = 0.7, no main effect for condition, F (1, 42) = 2.1, p = 0.2, and no species by condition…

The opposition has focused on research looking into the empirical evidence the proponents present. In the research conducted by Trzesniewski, Donnellan, & Robins (2008), they evaluated the empirical basis of the research and findings of Twenge and colleagues(year), specifically the limitations of convenience sampling. The first issue raised involved their technique of cross-temporal meta-analysis, which compiles data from a questionnaire for an extensive number of years. With this concern…

Call bells ringing, heart monitors beeping, patients crying out in pain, and nurses sprinting from room to room. All of these are common sights and sounds in hospitals these days: especially with the increasing numbers of hospitalized patients and a decrease in the amount of nursing staff available. While being down a nurse or two on a unit may not seem like the end of the world to some, it is a huge crisis in hospitals these days. Understaffed nurses are being forced to take on more patients…
