Research

Thomas Jefferson Building, Washington, D.C.

Research and experimental development is formal work undertaken systematically to increase the stock of knowledge, including knowledge of humanity, culture and society, and the use of this stock of knowledge to devise new applications (OECD (2002) Frascati Manual: proposed standard practice for surveys on research and experimental development, 6th edition.)[1] It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories. A research project may also be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects, or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, or the research and development of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences.

There are several forms of research: scientific, humanities, artistic, economic, social, business, etc.

[edit] Forms of research

Scientific research relies on the application of the scientific method, a harnessing of curiosity. This research provides scientific information and theories for the explanation of the nature and the properties of the world. It makes practical applications possible. Scientific research is funded by public authorities, by charitable organizations and by private groups, including many companies. Scientific research can be subdivided into different classifications according to their academic and application disciplines. Scientific research is a widely used criterion for judging the standing of an academic institution, such as business schools, but some argue that such is an inaccurate assessment of the institution, because the quality of research does not tell about the quality of teaching (these do not necessarily correlate totally).[2]

Research in the humanities involves different methods such as for example evidence to systematically investigate a topic, and then to write histories in the form of accounts of the past.

Artistic research, also seen as ‘practice-based research’, can take form when creative works are considered both the research and the object of research itself. It is the debatable body of thought which offers an alternative to purely scientific methods in research in its search for knowledge and truth.

The phrase my research is also used loosely to describe a person’s entire collection of information about a particular subject.

[edit] Etymology

Aristotle, 384 BC – 322 BC, – one of the early figures in the development of the scientific method.[3]

The word research is derived from the [4]

[edit] Definitions

Research has been defined in a number of different ways.

A broad definition of research is given by Martyn Shuttleworth – “In the broadest sense of the word, the definition of research includes any gathering of data, information and facts for the advancement of knowledge.”[5]

Another definition of research is given by Creswell who states – “Research is a process of steps used to collect and analyze information to increase our understanding of a topic or issue”. It consists of three steps: Pose a question, collect data to answer the question, and present an answer to the question.[6]

The Merriam-Webster Online Dictionary defines research in more detail as “a studious inquiry or examination; especially  : investigation or experimentation aimed at the discovery and interpretation of facts, revision of accepted theories or laws in the light of new facts, or practical application of such new or revised theories or laws”.[4]

[edit] Steps in conducting research

Research is often conducted using the hourglass model structure of research.[8]

  • Identification of research problem
  • Literature review
  • Specifying the purpose of research
  • Determine specific research questions or hypotheses
  • Data collection
  • Analyzing and interpreting the data
  • Reporting and evaluating research

The steps generally represent the overall process, however they should be viewed as an ever-changing process rather than a fixed set of steps.Null hypothesis are then reported and evaluated. At the end the researcher may discuss avenues for further research.

Rudolph Rummel says, “… no researcher should accept any one or two tests as definitive. It is only when a range of tests are consistent over many kinds of data, researchers, and methods can one have confidence in the results.”[11]

Generally, research is understood to follow a certain structural process. Though step order may vary depending on the subject matter and researcher, the following steps are usually part of most formal research, both basic and applied:

  1. Observations and Formation of the topic: Consists of the subject area of ones interest and following that subject area to conduct subject related research. The subject area should not be randomly chosen since it requires reading a vast amount of literature on the topic to determine the gap in the literature the researcher intends to narrow. A keen interest in the chosen subject area is advisable. The research will have to be justified by linking its importance to already existing knowledge about the topic.
  2. Hypothesis: A testable prediction which designates the relationship between two or more variables.
  3. Conceptual definition: Description of a concept by relating it to other concepts.
  4. Operational definition: Details in regards to defining the variables and how they will be measured/assessed in the study.
  5. Gathering of data: Consists of identifying a population and selecting samples, gathering information from and/or about these samples by using specific research instruments. The instruments used for data collection must be valid and reliable.
  6. Analysis of data: Involves breaking down the individual pieces of data in order to draw conclusions about it.
  7. Data Interpretation: This can be represented through tables, figures and pictures, and then described in words.
  8. Test, revising of hypothesis
  9. Conclusion, reiteration if necessary

A common misconception is that a hypothesis will be proven (see, rather, falsifiability). However, if the outcome is consistent with the hypothesis, the experiment is said to support the hypothesis. This careful language is used because researchers recognize that alternative hypotheses may also be consistent with the observations. In this sense, a hypothesis can never be proven, but rather only supported by surviving rounds of scientific testing and, eventually, becoming widely thought of as true.

A useful hypothesis allows prediction and within the accuracy of observation of the time, the prediction will be verified. As the accuracy of observation improves with time, the hypothesis may no longer provide an accurate prediction. In this case a new hypothesis will arise to challenge the old, and to the extent that the new hypothesis makes more accurate predictions than the old, the new will supplant it. Researchers can also use a null hypothesis, which state no relationship or difference between the independent or dependent variables. A null hypothesis uses a sample of all possible people to make a conclusion about the population.[12]

[edit] Historical method

German historian history.

The historical method comprises the techniques and guidelines by which historians use historical sources and other evidence to research and then to write history. There are various history guidelines commonly used by historians in their work, under the headings of external criticism, internal criticism, and synthesis. This includes lower criticism and sensual criticism. Though items may vary depending on the subject matter and researcher, the following concepts are part of most formal historical research:[13]

[edit] Research methods

The goal of the research process is to produce new knowledge or deepen understanding of a topic or issue. This process takes three main forms (although, as previously discussed, the boundaries between them may be obscure):

The research room at the New York Public Library, an example of secondary research in progress.

There are two ways to conduct research:

Primary research
Using primary sources, i.e., original documents and data.
Secondary research
Using secondary sources, i.e., a synthesis of, interpretation of, or discussions about primary sources.

There are two major research designs: qualitative research and quantitative research. Researchers choose one of these two tracks according to the nature of the research problem they want to observe and the research questions they aim to answer:

Maurice Hilleman is credited with saving more lives than any other scientist of the 20th century.[14]

Qualitative research
Understanding of human behavior and the reasons that govern such behavior. Asking a broad question and collecting word-type data that is analyzed searching for themes. This type of research looks to describe a population without attempting to quantifiably measure variables or look to potential relationships between variables. It is viewed as more restrictive in testing hypotheses because it can be expensive and time consuming, and typically limited to a single set of research subjects. Qualitative research is often used as a method of exploratory research as a basis for later quantitative research hypotheses.
Quantitative research
Systematic empirical investigation of quantitative properties and phenomena and their relationships. Asking a narrow question and collecting numerical data to analyze utilizing statistical methods. The quantitative research designs are experimental, correlational, and survey (or descriptive).[15] Statistics derived from quantitative research can be used to establish the existence of associative or causal relationships between variables.

The Quantitative data collection methods rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories. These methods produce results that are easy to summarize, compare, and generalize. Quantitative research is concerned with testing hypotheses derived from theory and/or being able to estimate the size of a phenomenon of interest. Depending on the research question, participants may be randomly assigned to different treatments (this is the only way that a quantitative study can be considered a true experiment). If this is not feasible, the researcher may collect data on participant and situational characteristics in order to statistically control for their influence on the dependent, or outcome, variable. If the intent is to generalize from the research participants to a larger population, the researcher will employ probability sampling to select participants.[16]

[edit] Research funding

Most funding for scientific research comes from three major sources: corporate research and development departments; private foundations, for example, the Bill and Melinda Gates Foundation; and government research councils such as the National Institutes of Health in the USA[20] and the Medical Research Council in the UK. These are managed primarily through universities and in some cases through military contractors. Many senior researchers (such as group leaders) spend a significant amount of their time applying for grants for research funds. These grants are necessary not only for researchers to carry out their research, but also as a source of merit.

The Social Psychology Network provides a comprehensive list of U.S. Government and private foundation funding sources.

[edit] Original research

Original research is research that is not exclusively based on a summary, review or synthesis of earlier publications on the subject of research. This material is of a [22]

[edit] Different forms

Original research can take a number of forms, depending on the discipline it pertains to. In experimental work, it typically involves direct or indirect observation of the researched subject, e.g., in the laboratory or in the field, documents the methodology, results, and conclusions of an experiment or set of experiments, or offers a novel interpretation of previous results. In analytical work, there are typically some new (for example) mathematical results produced, or a new way of approaching an existing problem. In some subjects which do not typically carry out experimentation or analysis of this kind, the originality is in the particular way existing understanding is changed or re-interpreted based on the outcome of the work of the researcher.[23]

The degree of originality of the research is among major criteria for articles to be published in [25]

[edit] Artistic research

The controversial trend of artistic teaching becoming more academics-oriented is leading to artistic research being accepted as the primary mode of enquiry in art as in the case of other disciplines.[27]

Artistic research has been defined by the [29]
