As with the first the Second Edition of Research Methodology is designed specifically for students with no previous experience or knowledge of research and research methodology. Some of the major research areas covered by the book are: User Review - Flag as inappropriate It is a god book for teacher N student but how can I get this book in soft copy. User Review - Flag as inappropriate When we think about the theoretical perspective for our research then reliance on Literature review becomes indispensible.
Other editions - View all Research Methodology: Marzano Limited preview - This is a summary of the key concepts in scientific research and an attempt to erase some common misconceptions in science. Steps of the scientific method are shaped like an hourglass - starting from general questions, narrowing down to focus on one specific aspect , and designing research where we can observe and analyze this aspect.
At last, we conclude and generalize to the real world. Researchers organize their research by formulating and defining a research problem. This helps them focus the research process so that they can draw conclusions reflecting the real world in the best possible way. In research, a hypothesis is a suggested explanation of a phenomenon. A null hypothesis is a hypothesis which a researcher tries to disprove. Research methodology involves the researcher providing an alternative hypothesis, a research hypothesis , as an alternate way to explain the phenomenon.
The research hypothesis is often based on observations that evoke suspicion that the null hypothesis is not always correct. In the Stanley Milgram Experiment , the null hypothesis was that the personality determined whether a person would hurt another person, while the research hypothesis was that the role, instructions and orders were much more important in determining whether people would hurt others.
A variable is something that changes. It changes according to different factors. Some variables change easily, like the stock-exchange value, while other variables are almost constant, like the name of someone. Researchers are often seeking to measure variables. The variable can be a number, a name, or anything where the value can change. An example of a variable is temperature.
The temperature varies according to other variable and factors. You can measure different temperature inside and outside. If it is a sunny day, chances are that the temperature will be higher than if it's cloudy.
Another thing that can make the temperature change is whether something has been done to manipulate the temperature, like lighting a fire in the chimney. In research, you typically define variables according to what you're measuring.
The independent variable is the variable which the researcher would like to measure the cause , while the dependent variable is the effect or assumed effect , dependent on the independent variable.
These variables are often stated in experimental research , in a hypothesis , e. In explorative research methodology, e.
They might not be stated because the researcher does not have a clear idea yet on what is really going on. Confounding variables are variables with a significant effect on the dependent variable that the researcher failed to control or eliminate - sometimes because the researcher is not aware of the effect of the confounding variable. The key is to identify possible confounding variables and somehow try to eliminate or control them.
Researchers can also use a null hypothesis, which states no relationship or difference between the independent or dependent variables. 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 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 may vary depending on the subject matter and researcher, the following concepts are part of most formal historical 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. As such, it is similar to the social sciences in using qualitative research and intersubjectivity as tools to apply measurement and critical analysis.
It is based on artistic practices, methods, and criticality. Through presented documentation, the insights gained shall be placed in a context. According to artist Hakan Topal , in artistic research, "perhaps more so than other disciplines, intuition is utilized as a method to identify a wide range of new and unexpected productive modalities". This may 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: Research is often conducted using the hourglass model structure of research. The major steps in conducting research are: 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.
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 may 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 analyzes and interprets the data via a variety of statistical methods, engaging in what is known as empirical research. The results of the data analysis in rejecting or failing to reject the null hypothesis are then reported and evaluated.
At the end, the researcher may discuss avenues for further research. However, some researchers advocate for the reverse approach: The reverse approach is justified by the transactional nature of the research endeavor where research inquiry, research questions, research method, relevant research literature, and so on are not fully known until the findings have fully emerged and been interpreted. Rudolph Rummel says, " 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.
Plato in Meno talks about an inherent difficulty, if not a paradox, of doing research that can be paraphrased in the following way, "If you know what you're searching for, why do you search for it?! 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:. There are two major types of empirical research design: 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:.
Social media posts are used for qualitative research. The quantitative data collection methods rely on random sampling and structured data collection instruments that fit diverse experiences into predetermined response categories.
If the research question is about people, participants may be randomly assigned to different treatments this is the only way that a quantitative study can be considered a true experiment. If the intent is to generalize 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 may 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 practice to use secondary data wherever possible. For example, a researcher may choose to conduct a qualitative study and follow it up with a quantitative study to gain additional insights.
Big data has brought big impacts on research methods so that now many researchers do not put much effort into data collection; furthermore, methods to analyze easily available huge amounts of data have also been developed. Non-empirical theoretical research is an approach that involves the development of theory as opposed to using observation and experimentation.
As such, non-empirical research seeks solutions to problems using existing knowledge as its source. This, however, does not mean that new ideas and innovations cannot be found within the pool of existing and established knowledge. Non-empirical research is not an absolute alternative to empirical research because they may be used together to strengthen a research approach.
Neither one is less effective than the other since they have their particular purpose in science. Typically empirical research produces observations that need to be explained; then theoretical research tries to explain them, and in so doing generates empirically testable hypotheses; these hypotheses are then tested empirically, giving more observations that may need further explanation; and so on.
A simple example of a non-empirical task is the prototyping of a new drug using a differentiated application of existing knowledge; another is the development of a business process in the form of a flow chart and texts where all the ingredients are from established knowledge.
Much of cosmological research is theoretical in nature. Mathematics research does not rely on externally available data; rather, it seeks to prove theorems about mathematical objects.
Research ethics involves the application of fundamental ethical principles to a variety of topics involving research, including scientific research.
These principles include deontology , consequentialism , virtue ethics and value ethics. Ethical issues may arise in the design and implementation of research involving human experimentation or animal experimentation , such as: Research ethics is most developed as a concept in medical research.
The key agreement here is the Declaration of Helsinki. The Nuremberg Code is a former agreement, but with many still important notes. Research in the social sciences presents a different set of issues than those in medical research  and can involve issues of researcher and participant safety, empowerment and access to justice.
When research involves human subjects, obtaining informed consent from them is essential. In many disciplines, Western methods of conducting research are predominant.
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 may not be the most accurate or relevant for research on non-Western societies. 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 to be accepted to elite Western-dominated journals.
Peer review is a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are employed to maintain standards of quality, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication.
Usually, the peer review process involves experts in the same field who are consulted by editors to give a review of the scholarly works produced by a colleague of theirs from an unbiased and impartial point of view, and this is usually done free of charge. The tradition of peer reviews being done for free has however brought many pitfalls which are also indicative of why most peer reviewers decline many invitations to review.
The methods section describes actions to be taken to investigate a research problem and the rationale for the application of specific procedures or techniques used to identify, select, process, and analyze information applied to understanding the problem, thereby, allowing the reader to critically.
Definition of research methodology: The process used to collect information and data for the purpose of making business decisions. The methodology may include publication research, interviews, surveys and other research techniques, and.
The methodology is the general research strategy that outlines the way in which research is to be undertaken and, among other things, identifies the methods to be used in it. These methods, described in the methodology, define the means or modes of data collection or. Key concepts of the research methodology. Understanding the significance of the Scientific Method.
A research method is a systematic plan for doing research. In this lesson, we'll look at the definition for a research method and examine the four. The research question, ethics, budget and time are all major considerations in any design.. This is before looking at the statistics required, and studying the preferred methods for the individual scientific discipline.. Every experimental design must make compromises and generalizations, so the researcher must try to minimize these, whilst remaining realistic.
