Academic research[ change change source ] Researchers take part in field or laboratory experimentsreading relevant books, journals or websitestaking notes and making conclusions. Teaching and lecturing is only part of the job of a professor or researcher. It is meant to improve understanding of biologyengineeringphysicschemistry and many other fields. With this kind of research, scientists can understand the world, and discover useful things.
Longitudinal study Confirmatory versus exploratory research[ edit ] Confirmatory research tests a priori hypotheses — outcome predictions that are made before the measurement phase begins. Such a priori hypotheses are usually derived from a theory or the results of previous studies.
The advantage of confirmatory research is that the result is more meaningful, in the sense that it is much harder to claim that a certain result is generalizable beyond the data set. The reason for this is that in confirmatory research, one ideally strives to reduce the probability of falsely reporting a coincidental result as meaningful.
Exploratory research, on the other hand, seeks to generate a posteriori hypotheses by examining a data-set and looking for potential relations between variables. It is also possible to have an idea about a relation between variables but to lack knowledge of the direction and strength of the relation.
If the researcher does not have any specific hypotheses beforehand, the study is exploratory with respect to the variables in question although it might be confirmatory for others.
The advantage of exploratory research is that it is easier to make new discoveries due to the less stringent methodological restrictions. In other words, if the researcher simply wants to see whether some measured variables could be related, he would want to increase the chances of finding a significant result by lowering the threshold of what is deemed to be significant.
Sometimes, a researcher may conduct exploratory research but report it as if Definition of research methodology wikipedia had been confirmatory 'Hypothesizing After the Results are Known', HARKing—see Hypotheses suggested by the data ; this is a questionable research practice bordering on fraud.
State problems versus process problems[ edit ] A distinction can be made between state problems and process problems. State problems aim to answer what the state of a phenomenon is at a given time, while process problems deal with the change of phenomena over time. Examples of state problems are the level of mathematical skills of sixteen-year-old children or the level, computer skills of the elderly, the depression level of a person, etc.
Examples of process problems are the development of mathematical skills from puberty to adulthood, the change in computer skills when people get older and how depression symptoms change during therapy.
State problems are easier to measure than process problems. State problems just require one measurement of the phenomena of interest, while process problems always require multiple measurements.
Research designs such as repeated measurements and longitudinal study are needed to address process problems. Examples of fixed designs[ edit ] Experimental research designs[ edit ] See also: Experiment In an experimental design, the researcher actively tries to change the situation, circumstances, or experience of participants manipulationwhich may lead to a change in behaviour or outcomes for the participants of the study.
The researcher randomly assigns participants to different conditions, measures the variables of interest and tries to control for confounding variables.
Therefore, experiments are often highly fixed even before the data collection starts. In a good experimental designa few things are of great importance. First of all, it is necessary to think of the best way to operationalize the variables that will be measured, as well as which statistical methods would be most appropriate to answer the research question.
Thus, the researcher should consider what the expectations of the study are as well as how to analyse any potential results.
Finally, in an experimental design, the researcher must think of the practical limitations including the availability of participants as well as how representative the participants are to the target population. It is important to consider each of these factors before beginning the experiment. Non-experimental research designs[ edit ] Non-experimental research designs do not involve a manipulation of the situation, circumstances or experience of the participants.

Non-experimental research designs can be broadly classified into three categories. First, in relational designs, a range of variables are measured. These designs are also called correlation studies because correlation data are most often used in the analysis.
Since correlation does not imply causationsuch studies simply identify co-movements of variables. Correlational designs are helpful in identifying the relation of one variable to another, and seeing the frequency of co-occurrence in two natural groups See correlation and dependence.
The second type is comparative research. These designs compare two or more groups on one or more variable, such as the effect of gender on grades.
The third type of non-experimental research is a longitudinal design. A longitudinal design examines variables such as performance exhibited by a group or groups over time. Examples of flexible research designs[ edit ] See also: Case study Famous case studies are for example the descriptions about the patients of Freud, who were thoroughly analysed and described.
Ethnography This type of research is involved with a group, organization, culture, or community. Normally the researcher shares a lot of time with the group. Grounded theory study[ edit ] Grounded theory research is a systematic research process that works to develop "a process, and action or an interaction about a substantive topic".Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it.
The technique has been applied in the study of mathematics and logic since before Aristotle (– B.C.), though analysis as a formal concept is a relatively recent development.. The word comes from the Ancient Greek ἀνάλυσις (analysis, "a breaking up.

Overview. Action research is an interactive inquiry process that balances problem solving actions implemented in a collaborative context with data-driven collaborative analysis or research to understand underlying causes enabling future predictions about personal and organizational change (Reason & Bradbury, ).
After six decades of action research . 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.
In the workshop various aspects have been discussed related to research methodology, including critical thinking in research, research process, how to write a research paper, and research ethics, etc.
A research design is the set of methods and procedures used in collecting and analyzing measures of the variables specified in the research problem research.
The design of a study defines the study type (descriptive, correlation, semi-experimental, experimental, review.
