Scientific methods, 12-16 conclusion

The scientific method is taught starting in elementary school. The first step in the scientific method is to form a hypothesis. A hypothesis is just an educated guess or logical conclusion from known facts. It is then compared against all available data and its details developed. If the hypothesis is found to be consistent with known facts, it is called a theory and usually published. The characteristics most theories have in common are that they explain observed phenomena, predict the results of future experiments, and can be presented in mathematical form. When a theory is found to be always correct for many years, it is eventually referred to as a scientific law. However useful this process is, we often use constructs that do not fit in the scientific method scheme as it is typically described. 

Our discussion to this point has been confined to those areas in which the governing laws are well known. However, in many areas, information on the governing laws is lacking. Interest in the application of statistical methods to all types of problems has grown rapidly since World War II. Broadly speaking, statistical methods may be of use whenever conclusions are to be drawn or decisions made on the basis of experimental evidence. Since statistics could be defined as the technology of the scientific method, it is primarily concerned with the first two aspec ts of the method, namely, the performance of experiments and the drawing of conclusions from experiments. Traditionally the field is divided into two areas ... 

The purpose of this discussion of science, clearly, is to apply it to herbal medicine. The reputed uses of drugs may not always be accurate or effective. Applying the scientific method to herbal medicine therefore allows us to test the traditional uses and to know with greater certainty what an herbal medication does and how reliably it does it. Although far from infallible, the process as a whole gives us greater confidence in our conclusions. 

With the more widespread use of subnitrogen cryogenic temperatures, use of smaller samples made possible by brighter sources, and rapid developments in detector technology and computational methods, the conclusions of the oxalic acid project are now of mainly historical importance. However, the project remains an example of the value of collaborative efforts in establishing the validity of a scientific method. 

Robert Boyle (1627-1691), an English scientist, noticed that gases can be compressed. He used J-shaped tubes to show that gas pressure and gas volume at a constant temperature and amount are inversely related. His experiments were performed with one variable, and his conclusions were drawn from experimental observations. He argued that theories should be the result of experimental observations, and therefore he considered is the founder of the modem scientific method. 

Ask if the work was published in a peer-reviewed journal. Peer review is the standard process for scientific publications. Peer-reviewed manuscripts have been read by several scholars in the same field (called peers), and these peers have indicated that the experiments and conclusions meets the standards of their discipline and are suitable for publication. In the absence of peer-review the significance and quality of the data cannot be assessed. With no peer-reviewed, published record of the boy s subjective experiment, it is doubtful that normal standard scientific methods were applied. 

Some believe that risk assessment is not complex or difficult while others believe that it is complicated and hard to understand. Irrespective of a person s exposure to the risk assessment process, risk assessment procedures are complicated and complex beyond the scope of individual person s input. Simply put, risk assessment is both a science and an art. Risk assessment has properties of science, because the process totally depends on data generated by good scientific practice. The difficulty is, while scientists can possibly wait until final conclusions are reached using agreed scientific methods, the society and the risk manager cannot wait that long. The science and art aspect of risk assessment is illustrated in the table below. 

In this section, it is important to do two things outline the method of randomization so that the procedure is clear and is set out as a standard for all sites (in the case of multicenter trials) and make certain that the method of randomization is shown to be truly random and thus supportive of scientifically valid conclusions and equitable to the patients. 

To judge from the history of science, the scientific method is excellent as a means of obtaining plausible conclusions which are always wrong, but hardly as a means of reaching the truth. 

Science is unlike other fields of study in that it includes specific procedures for conducting research. These procedures make up the scientific method, which is shown in Figure 8. The scientific method is not a series of exact steps, but rather a strategy for drawing sound conclusions. 

The first scientists depended on rational thought and logic. They rarely felt it was necessary to test their ideas or conclusions, and they did not feel the need to experiment. Gradually, experiments became the crucial test for the acceptance of scientific knowledge. Today, experiments are an important part of the scientific method. 

Typical steps of a scientific method include observation, hypothesis, experiments, data analysis, and conclusion. 

From the viewpoint of scientific methodology there are three main tasks in CAPE representation of the problem, generation of several alternative solutions, and selection of the best one. These tasks correspond to the activities realized in four phases of any scientific method analysis (description of the problem and identification of the objectives), hypothesis (generation of solutions), synthesis (comparing the solutions), and validation (formulation of conclusions). The activities realized in the last two phases correspond to the selection task in CAPE. 

Finally, knowledge of experimental design and the scientific method is important in evaluating the credibility of studies. For example, one should look for the inclusion of control groups and the presence of data to support the given conclusions. 

I believe not, especially because the scientific method, as such, deliberately leaves out considerations of purpose. If, in their more popular essays on the implications of science, scientists hold forth on the question of purpose in nature, it is not as scientists, but as (usually amateur) philosophers that they do so. And that they attempt to draw philosophical conclusions directly out of the data of science is sometimes indicative more of a prior commitment to explanatory monism than of a genuine respect for the integrity of science. 

When the above four basic observational facts are combined and considered together, there is no escape from the conclusion that our universe is expanding and cooling. This conclusion is entirely consistent with the Hot Big Bang model. Sometimes, we hear the stronger statement that these observations prove that there was a Hot Big Bang. However, the scientific method does not truly produce proofs in the mathematical sense. 

This basic limitation of the scientific method is often misinterpreted when findings from risk assessment studies are reported in the popular press. A scientific conclusion may be stated in terms that it is highly unlikely that or... 

Once you know the function of your paper and have identified its audience, review your material for completeness or excess. Then, organize your material into the standard format introduction, experimental details or theoretical basis, results, discussion, and conclusions. This format has become standard because it is suitable for most reports of original research, it is basically logical, and it is easy to use. The reason it accommodates most reports of original research is that it parallels the scientific method of deductive reasoning define the problem, create a hypothesis, devise an experiment to test the hypothesis, conduct the experiment, and draw conclusions. Furthermore, this format enables the reader to understand quickly what is being presented and to find specific information easily. This ability is crucial now more than ever because scientists, if not all professionals, must read much more material than their time seems to allow.
