Original research is research that is not exclusively based on a summary, review or synthesis of earlier publications on the subject of research.These two variable, smoking and lung disease were found to covary together.The kinds of publications that are accepted as contributions of knowledge or research vary greatly between fields, from the print to the electronic format.Perhaps more of the older group smoked in their early years as compared to the younger group due to increased awareness of the hazards of cigarettes.For example, if you conduct a study looking at heart disease in men, can these results be generalized to women.In other words, neither the patient or the person administering the drug should know whether the patient is receiving the drug or the placebo.What links here Related changes Upload file Special pages Permanent link Page information Wikidata item Cite this page.
In the social and bahavioral sciences, it is important to always provide sufficient information to allow other researchers to adopt or replicate your methodology.If the individuals who were responsible for the dependent measures were also unaware of whether the child was in the treatment or control group, then the experiment would have been double blind.You should make the assumption that readers possess a basic understanding of how to investigate the research problem on their own and, therefore, you do not have to go into great detail about specific methodological procedures.
You must explain how you obtained and analyzed your results for the following reasons.Learn more about determining the research design in the Boundless open textbook.You may improve this article, discuss the issue on the talk page, or create a new article, as appropriate.

If other data sources exist, explain why the data you chose is most appropriate to addressing the research problem.Also, you probably would not want to buy a car that had the door slammed five hundred thousand time or had been crash tested.As no random assignment exists in a quasi-experiment, no causal statements can be made based on the results of the study.For example, the early studies on cigarette smoking did not manipulate how many cigarettes were smoked.I edit a community blog for naturalistic spirituality, devoted to a marriage of science and myth.Help About Wikipedia Community portal Recent changes Contact page.For example, all individuals who reside in the United States make up a population.

External Validity: External validity addresses the issue of being able to generalize the results of your study to other times, places, and persons.I feel it applies not only to proving Otherkin as something other than collective imagination, but also proving the objective existence of magic.However, if the outcome is consistent with the hypothesis, the experiment is said to support the hypothesis.
A design is used to structure the research, to show how all of the major parts of the.
Any member of the defined population can be included in a sample.
The scores on these measures were influenced by and depended on whether the child was in the treatment or control group.There are several forms of research: scientific, humanities, artistic, economic, social, business, marketing, practitioner research, life, technological,etc.Secondary data is data that already exists, such as census data, which can be re-used for the research.One dependent variable that could be used is an Activities of Daily Living Checklist.This involves understanding human behavior and the reasons that govern such behavior, by asking a broad question, collecting data in the form of words, images, video etc that is analyzed, and searching for themes.
