Research comprises "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications." 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 might additionally be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research might 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 (R&D) 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, marketing, practitioner research, life, technological,etc.

Forms of research

Scientific research is a systematic way of gathering data and harnessing 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 organisations and by private groups, including a large number of 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 a few argue that such is an inaccurate assessment of the institution, because the quality of research doesn't tell about the quality of teaching (these don't necessarily correlate).

Research in the humanities involves different methods such as for example hermeneutics and semiotics. Humanities scholars usually don't search for the ultimate correct answer to a question, but instead explore the issues and details that surround it. Context is always important, and context can be social, historical, political, cultural, or ethnic. An example of research in the humanities is historical research, which is embodied in historical method. Historians use primary sources and additional evidence to systematically investigate a topic, and then to write histories in the form of accounts of the past.

Artistic research, additionally 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.

Etymology

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

The word research is derived from the Middle French "recherche", which means "to go about seeking", the term itself being derived from the Old French term "recerchier" a compound word from "re-" + "cerchier", or "sercher", meaning 'search'. The earliest recorded use of the term was in 1577.

Definitions

Research has been defined in a number of different ways.

A broad definition of research is given by Godwin Colibao - "In the broadest sense of the word, the definition of research includes any gathering of data, information and facts for the advancement of knowledge."

Another definition of research is given by Creswell who states that - "Research is a process of steps used to gather and analyse information to increase our understanding of a topic or issue". It consists of three steps: Pose a question, collect data to reply the question, and present an answer to the question.

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".

Steps in conducting research

Research is often conducted using the hourglass model structure of research. The hourglass model starts with a broad spectrum for research, focusing in on the required information through the method of the project (like the neck of the hourglass), then expands the research in the form of discussion and results. The major steps in conducting research are:

  • Identification of research problem
  • Literature review
  • Specifying the purpose of research
  • Determine specific research questions
  • Specification of a conceptual framework, usually a set of hypotheses
  • Choice of a methodology (for data collection)
  • Data collection
  • Verify data
  • Analyzing and interpreting the data
  • Reporting and evaluating research
  • Communicating the research findings and, possibly, recommendations

The steps generally represent the overall process; however, they should be viewed as an ever-changing iterative process rather than a fixed set of steps. Most research begins with a general statement of the problem, or rather, the purpose for engaging in the study. The literature review identifies flaws or holes in previous research which provides justification for the study. Often, a literature review is conducted in a given subject area before a research question is identified. A gap in the current literature, as identified by a researcher, then engenders a research question. The research question might be parallel to the hypothesis. The hypothesis is the supposition to be tested. The researcher(s) collects data to test the hypothesis. The researcher(s) then analyses and interprets the data via a variety of statistical methods, engaging in what's known as empirical research. The results of the data analysis in confirming or failing to reject the Null hypothesis are then reported and evaluated. At the end, the researcher might discuss avenues for further research. Notwithstanding a few researchers advocate for the flip approach: starting with articulating findings and discussion of them, moving "up" to identification research problem that emerging in the findings and literature review introducing the findings. The flip approach is justified by the transactional nature of the research endeavour where research inquiry, research questions, research method, relevant research literature, and so on aren't fully known until the findings fully emerged and interpreted.

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 a large number of kinds of data, researchers, and methods can one have confidence in the results."

Plato in Meno talks about an inherent difficulty, if not a paradox, of doing research that can be paraphrase in the following way, "If you know what you're searching for, why do you search for it?! [i.e., you have already found it] If you don't know what you're searching for, what're you searching for?!"

Generally, research is understood to follow a certain structural process. Though step order might 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 shouldn't be randomly chosen after 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 additional concepts.
  4. Operational definition: Details in regards to defining the variables and how they'll 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, Null hypothesis). Generally, a hypothesis is used to make predictions that can be tested by observing the outcome of an experiment. If the outcome is inconsistent with the hypothesis, then the hypothesis is rejected (see falsifiability). Notwithstanding if the outcome is consistent with the hypothesis, the experiment is said to support the hypothesis. This careful language is used because researchers recognise that alternative hypotheses might additionally 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, fitting 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 might 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 additionally 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.

Historical method

German historian Leopold von Ranke (1795-1886), considered to be one of the founders of modern source-based history.

The historical method comprises the techniques and guidelines by which historians use historical sources and additional evidence to research and then to write history. There are various history guidelines that are 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 might vary depending on the subject matter and researcher, the following concepts are part of most formal historical research:

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 might be obscure):

There are two major types of empirical research design: qualitative research and quantitative research. Researchers choose qualitative or quantitative methods according to the nature of the research topic they want to investigate and the research questions they aim to answer:

Qualitative research
Understanding of human behaviour and the reasons that govern such behavior. Asking a broad question and collecting data in the form of words, images, video etc that's analysed and searching for themes. This type of research aims to investigate a question 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. Qualitative research is linked with the philosophical and theoretical stance of social constructionism.
Quantitative research
Systematic empirical investigation of quantitative properties and phenomena and their relationships. Asking a narrow question and collecting numerical data to analyse utilising statistical methods. The quantitative research designs are experimental, correlational, and survey (or descriptive). Statistics derived from quantitative research can be used to establish the existence of associative or causal relationships between variables. Quantitative research is linked with the philosophical and theoretical stance of positivism.

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 might be randomly assigned to different treatments (this is the only way that a quantitative study can be considered a true experiment). If this isn't feasible, the researcher might 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 generalise from the research participants to a larger population, the researcher will employ probability sampling to select participants.

In either qualitative or quantitative research, the researcher(s) might collect primary or secondary data. Primary data is data collected specifically for the research, such as through interviews or questionnaires. Secondary data is data that already exists, such as census data, which can be re-used for the research. It is good ethical research practise to use secondary data wherever possible.

Mixed-method research, i.e. research that includes qualitative and quantitative elements, using both primary and secondary data, is fitting more common.

Big data has brought big impacts on research methods that now researchers don't put much effort on data collection, and additionally methods to analyse easily available huge amount of data have additionally changed.

Nonempirical refers to an approach that's grounded in theory as opposed to using observation and experimentation to achieve the outcome. As such, nonempirical research seeks solutions to problems using existing knowledge as its source. This, however, doesn't mean that new ideas and innovations can't be found within the pool existing and established knowledge. Nonempirical isn't an absolute alternative to empirical research because they might be used together to strengthen a research approach. Neither one is less effective than the additional after they have their particular purpose within life and in science. A simple example of a nonempirical task could the prototyping of a new drug using a differentiated application of existing knowledge; similarly, it can be the development of a business process in the form of a flow chart and texts where all the ingredients are from established knowledge. Empirical research on the additional hand seeks to create new knowledge through observations and experiments in which established knowledge can either be contested or supplements.

Research method controversies

There have been a large number of controversies about research methods stemmed from a philosophical positivism promise to distinguish the science from additional practises (especially religion) by its method. This promise leads to methodological hegemony and methodology wars where diverse researchers, often coming from opposing paradigms, try to impose their own methodology on the entire field or even on the science practise in general as the only legitimate one.

Quantitative vs. Qualitative war

Anti-methodology

According to this view, general scientific methodology doesn't exist and attempts to impose it on scientists is counterproductive. Each particular research with its emerging particular inquiries requires and should produce its own way (method) of researching. Similar to the art practice, the notion of methodology has to be replaced with the notion of research mastery.

Problems in research

Western Dominance

Research disciplines have been dominated by academics from Western countries, particularly by Americans. Geopolitical power dynamics have placed Western scholars as the elite gatekeepers of academia, relegating scholars from Periphery countries to inferior positions.

Methods of Research

In a large number of disciplines, Western methods of conducting research are predominant. Researchers are overwhelmingly taught Western methods of data collection and study. The increasing participation of Indigenous peoples as researchers has brought increased attention to the lacuna in culturally-sensitive methods of data collection. Non-Western methods of data collection might not be the most accurate or relevant for research on non-Western societies. For example, “Hua Oranga” was created as a criterium for psychological evaluation in Maori populations, and is based on dimensions of mental health important to the Maori people — "taha wairua (the spiritual dimension), taha hinengaro (the mental dimension), taha tinana (the physical dimension), and taha whanau (the family dimension)”.

Linguicism

Periphery scholars face the challenges of exclusion and Linguicism in research and academic publication. As the great majority of mainstream academic journals are written in English, multilingual periphery scholars often must translate their work in order to be accepted to elite Western-dominated journals. Multilingual scholars’ influences from their native communicative styles can be assumed to be incompetence instead of difference.

Publication

Publications from periphery countries rarely rise to the same elite status as those of North America and Europe primarily because of fewer material resources, rendering them less able to meet practical conventions of publishing such as paper weight and graphic quality. These subdue the voices of periphery scholars and prevent their contributions to collective knowledge.

Influence of the Open-Access Movement

The open access movement assumes that all information generally deemed useful should be free and belongs to a “public domain”, that of “humanity”. This idea gained prevalence as a result of Western colonial history and ignores alternative conceptions of knowledge circulation. For instance, most indigenous communities consider that access to certain information proper to the group should be determined by relationships.

There is a double standard found in the Western knowledge system. On the one hand, “digital right management” used to restrict access to personal information on social networking platforms are celebrated as a protection of privacy, while simultaneously when similar functions are utilised by cultural groups (ie indigenous communities) this is denounced as “access control” and reprehended as censorship.

Future Perspectives

Even though Western dominance seems to be prominent in research, a few scholars, such as Simon Marginson, argue for “the need [for] a plural university world”. Marginson argues that the East Asian Confucian model could take over the Western model.

This can be due to changes in funding for research both in the East and the West. Focussed on emphasising educational achievement, East Asian cultures, mainly in China and South Korea, have encouraged the increase of funding for research expansion. In contrast, in the Western academic world, notably in the United Kingdom as well as in a few state governments in the United States, funding cuts for university research is observed which might lead to the future decline of Western dominance in research.

Professionalisation

In several national and private academic systems, the professionalization of research has resulted in formal job titles.

In Russia

In present-day Russia, the former Soviet Union and in a few Post-Soviet states the term researcher (Russian: Научный сотрудник, nauchny sotrudnik) is both a generic term for a person who carried out scientific research, as well as a job position within the frameworks of the USSR Academy of Sciences, Soviet universities, and in additional research-oriented establishments. The term is additionally at times translated as research fellow, research associate, etc.

The following ranks are known:

  • Junior Researcher (Junior Research Associate)
  • Researcher (Research Associate)
  • Senior Researcher (Senior Research Associate)
  • Leading Researcher (Leading Research Associate)
  • Chief Researcher (Chief Research Associate)

Publishing

Cover of the first issue of Nature, 4 November 1869.

Academic publishing describes a system that's necessary in order for academic scholars to peer review the work and make it available for a wider audience. The system varies widely by field, and is additionally always changing, if often slowly. Most academic work is published in journal article or book form. There is additionally a large body of research that exists in either a thesis or dissertation form. These forms of research can be found in databases explicitly for theses and dissertations. In publishing, STM publishing is an abbreviation for academic publications in science, technology, and medicine.

Most established academic fields have their own scientific journals and additional outlets for publication, though a large number of academic journals are somewhat interdisciplinary, and publish work from several distinct fields or subfields. The kinds of publications that are accepted as contributions of knowledge or research vary greatly between fields; from the print to the electronic format. A study suggests that researchers shouldn't give great consideration to findings that aren't replicated frequently. It has additionally been suggested that all published studies should be subjected to a few measure for assessing the validity or reliability of its factors in order to prevent the publication of unproven findings. Business models are different in the electronic environment. Since about the early 1990s, licencing of electronic resources, particularly journals, has been quite common. Presently, a major trend, particularly with respect to scholarly journals, is open access. There are two main forms of open access: open access publishing, in which the articles or the whole journal is freely available from the time of publication, and self-archiving, where the author makes a copy of their own work freely available on the web.

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 and the Medical Research Council in the UK. These are managed primarily through universities and in a few 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 additionally as a source of merit.

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

Original research

Original research is research that isn't exclusively based on a summary, review or synthesis of earlier publications on the subject of research. This material is of a primary source character. The purpose of the original research is to produce new knowledge, rather than to present the existing knowledge in a new form (e.g., summarised or classified).

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(s), 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 a few new (for example) mathematical results produced, or a new way of approaching an existing problem. In a few subjects which don't 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.

The degree of originality of the research is among major criteria for articles to be published in academic journals and usually established by means of peer review. Graduate students are commonly required to perform original research as part of a dissertation.

Artistic research

The controversial trend of artistic teaching fitting more academics-oriented is leading to artistic research being accepted as the primary mode of enquiry in art as in the case of additional disciplines. One of the characteristics of artistic research is that it must accept subjectivity as opposed to the classical scientific methods. As such, it is similar to the social sciences in using qualitative research and intersubjectivity as tools to apply measurement and critical analysis.

Artistic research has been defined by the University of Dance and Circus (Dans och Cirkushögskolan, DOCH), Stockholm in the following manner - "Artistic research is to investigate and test with the purpose of gaining knowledge within and for our artistic disciplines. It is based on artistic practices, methods and criticality. Through presented documentation, the insights gained shall be placed in a context." Artistic research aims to enhance knowledge and understanding with presentation of the arts. For a survey of the central problematics of today's Artistic Research, see Giaco Schiesser.

According to artist Hakan Topal, in artistic research, "perhaps more so than additional disciplines, intuition is utilised as a method to identify a wide range of new and unexpected productive modalities". Most writers, whether of fiction or non-fiction books, additionally have to do research to support their creative work. This might be factual, historical, or background research. Background research could include, for example, geographical or procedural research.

The Society for Artistic Research (SAR) publishes the triannual Journal for Artistic Research (JAR), an international, online, open access, and peer-reviewed journal for the identification, publication, and dissemination of artistic research and its methodologies, from all arts disciplines and it runs the Research Catalogue (RC), a searchable, documentary database of artistic research, to which anyone can contribute.

Patricia Leavy addresses eight arts-based research (ABR) genres, they are: narrative inquiry, fiction-based research, poetry, music, dance, theatre, film, and visual art.
