¶ … scientific method. The one most common in nursing circles, that is derived from a desire to understand all facets of the question is the PICO method. The first letter of the acronym asks the researcher to label the specific population or the patient problem under examination. After the population or problem is defined, then the researcher must be able to suggest an intervention that is to be the focus of the research. In any good study there is also the opposite to the intervention which is made as a comparison. Finally, the researcher looks at the outcomes of the research to determine whether their hypothesis regarding the intervention was a success or a failure.
This method can be used for any research, and will, in this paper, be used to conduct an analysis of four articles. The population under examination are elderly nursing home patients. The intervention to be used is that these individuals participate in regular exercise. This intervention is compared to similar individuals who do not exercise at all. The expected outcome of the research conducted in the two quantitative and two qualitative articles is that the individuals who perform regular exercise will be better equipped to perform daily living activities. This paper seeks to synthesize four separate studies related to the stated PICO question.
All four of the studies were designed to look at how the populations could be helped when a regular exercise program was used. There was also a comparison with the original ability…
scientist' is but a simple word, unless mad is attached to it. When I hear someone say 'scientist' I think of mad scientists and they are never more than crazy villains set on destroying the world. There is a reason why science and through extension scientist is regarded by many as a subject leaning towards darkness and chaos. People in the past associated science and scientific breakthroughs with magic,
Many people might be casual users of marijuana and not use hard drugs, thus the research must be structured to see if causality as well as correlation is established between hard drug use and using marijuana beforehand. What do you think about the argument raised in the "Are scientists wearing blinkers?" section of the Web page? How does this idea tie into you chapter's discussion of neutrality and politics in
Snow, in contrast to Farr's epidemiology, was far more innovative and spontaneous in his methods, which also made his conclusions, in the eyes of his colleagues more suspect. As well as doing his own hands-on research, Snow analyzed the "natural experiment created when one water- supply company of London, the Lambeth Company -- but not the Southwark and Vauxhall Company -- moved its water inlet to a less polluted area

Retrieved on 4 Jul 2005 from Find Articles database at http://www.findarticles.com/p/articles/mi_m1134/is_n9_v107/ai Understanding the scientific method is one of the first building blocks of teaching modern scientific research to students. But do experienced scientists concern themselves with what makes rigorous hypothesis formulation and testing? In the scientific journal of Natural History, author and scientist
scientific method include a reliance on the empirical approach toward acquiring knowledge, and the skeptical attitude that scientists adopt toward explanations of behavior and mental processes (5). The empirical approach entails relying on direct observation and on objectivity. Once a scientist observes an object or a phenomenon and describes the phenomenon using clearly defined terms, he or she will probably formulate a hypothesis. The hypothesis is generally designed to
The Role of Forensic Science in Crime Scene Investigation The scientific method begins with the identification of a problem. Questions are asked, data is collected, a hypothesis is formed and then tested. The scientific method is essentially no different from the kind of investigative work that investigators of a crime scene do on a daily basis. They a faced with a problem: a crime has occurred. The questions they must ask
