| Action Research : |
That research role where the researcher and their role is involved in the research study and is interventionist. Here research is joined with action in order to plan, implement and monitor change. |
|
| Communication research : |
An umbrella term for market research, social research, media research and audience research combined. |
|
| Deductive reasoning : |
A logical process of developing specific predictions (hypotheses) from general principles. This type of reasoning moves from the general to the particular. |
|
| Dependent variable : |
In experimental research, the dependent variable is the variable presumed within the research hypothesis to depend on (be caused by) another variable (the independent variable); it is sometimes referred to as the outcome variable. |
|
| Descriptive Research : |
Research designed to provide a summary of some aspects of the environment when the hypotheses are tentative and speculative in nature. |
|
| Descriptive statistics : |
Statistical methods used to describe or summarize data collected from a specific sample (e.g. mean, median, mode, range, standard deviation). |
|
| Desk research : |
Research done by summarizing published sources - a form of secondary research. |
|
| Directional hypothesis (or one-tailed hypothesis) : |
A hypothesis that makes a specific prediction about the nature and direction of the relationship between the independent and dependent variables. |
|
| Educational Research : |
It is the formal, systematic application of the scientific method to the study of educational problems. |
|
| Empirical methods : |
Research methods and data gathering techniques supported by measurable evidence, not opinion or speculation. |
|
| Ethnographic research: : |
The collection of extensive narrative data on many variables over an extended period of time in a naturalistic setting in order to gain insights not possible using other types of research. For ethnographic research, observations are done at particular points of time. Data would include observations, recording and interpreting what is seen. |
|
| Experimental design : |
A study in which there is random assignment of subjects to different groups so that there are no major differences between the control and comparison groups. An experimental study controls all the conditions: •The environment •Sample assignment (random assignment in two groups) •Treatment/Intervention (Practice/Program) |
|
| Experimental group : |
In experimental research the group of subjects who receive the experimental treatment or intervention under investigation. |
|
| Experimental research : |
A research methodology used to establish cause-and-effect relationships between the independent and dependent variables by means of manipulation of variables, control and randomization. A true experiment involves the random allocation of participants to experimental and control groups, manipulation of the independent variable, and the introduction of a control group (for comparison purposes). Participants are assessed before and after the manipulation of the independent variable in order to assess its effect on the dependent variable (the outcome). |
|
| Extraneous variable : |
A variable that interferes with the relationship between the independent and dependent variables and which therefore needs to be controlled for in some way. |
|
| Group discussion : |
A generic type of qualitative research in which a small group of people provide information by discussing a topic. Some variants are the consensus group, focus group, nominal group, co-discovery conference. |
|
| Historical research : |
The systematic collection and evaluation of data related to past occurrences in order to describe causes, effects, trends of those events which may help to explain present events and anticipate future events. Data is often archival-including newspaper clippings, photographs, etc.-and may include interviews. |
|
| Hypothesis : |
A statement that predicts the relationship between variables (specifically the relationship between the independent and dependent variables). A hypothesis may be directional or non-directional. |
|
| Hypothesis Test : |
A formal test, using probability and sampling distributions to decide which of two conflicting hypotheses should be accepted. Sometimes referred to as a significance test (where the degree of error is emphasized). |
|
| Independent variable : |
The variable (or antecedent) that is assumed to cause or influence the dependent variable(s) or outcome. The independent variable is manipulated in experimental research to observe its effect on the dependent variable(s). It is sometimes referred to as the treatment variable. |
|
| Inductive reasoning : |
A logical process of reasoning used to develop more general rules from specific observations; this type of reasoning moves from the specific to the more generalized. |
|
| Inductivism/Inductive Reasoning : |
The process by which the truth of a proposition is made more probable by the accumulation of confirming evidence, a common pattern in sociological and scientific research. |
|
| Industrial research : |
Market research in which the respondents are organizations, not consumers. Much the same as business to business research. |
|
| Inferential statistics : |
Statistics that allow a researcher to make inferences about whether relationships observed in a sample are likely to occur in the wider population from which that sample was drawn. Inferential statistics use logic and mathematical processes in order to test hypotheses relating to a specific population based on data gathered from a sample of the population of interest. |
|
| Non-directional hypothesis (or two-tailed hypothes : |
A hypothesis that does not specify the nature and direction of the relationship between the independent and dependent variables. |
|
| Null hypothesis : |
A statement that there is no relationship between the independent and dependent variables and that any relationship observed is due to chance or fluctuations in sampling. |
|
| Participative Research/Participant Observation : |
Conscious and systematic sharing, in so far as circumstances will permit in the life activities, and on occasion, in the interests and affects of a group of persons. |
|
| Positivism : |
This paradigm assumes that human behavior is determined by external stimuli and that it is possible to use the principles and methods traditionally employed by the natural scientist to observe and measure social phenomena. |
|
| Positivism/Positivist Approach : |
A doctrine in the philosophy of science, positivism is characterized mainly by an insistence that science can only deal with observable entities known directly to experience. The positivist aims to construct general laws, or theories, which express relationships between phenomena. Observation and experiment will then show whether the phenomena do or do not fit the theory; explanation of phenomena consists in showing that they are instances of the general laws or regularities. |
|
| Primary Data : |
Data collected to address a specific research objective (as opposed to secondary data). |
|
| Qualitative data : |
Information gathered in narrative (nonnumeric) form (e.g. a transcript of an unstructured interview). |
|
| Qualitative Research : |
Qualitative research generally examines people’s words or actions in narrative or descriptive ways more closely representing the experiences of the people involved, it focuses on understandings, meanings and it takes seriously lay accounts and concepts. |
|
| Quantitative data : |
Information gathered in numeric form. |
|
| Quantitative Research : |
Quantitative research generally converts observations into discrete units that can be compared to other units by statistical analysis, it focuses on explanation, prediction and proof. |
|
| Reflexive Research : |
Reflexive research involves exploring the ability of people to collectively or individually transform social structures. The concepts of 'habitus' and 'structured improvisation' capture the intersection of structure and agency, & society and the individual. |
|
| Reliability : |
The degree to which the test consistently measures what is suppose to measure. |
|
| Replicability : |
A study is considered replicable if it can be repeated by another researcher. You can determine if a study is replicable by asking the following questions: •Is the description of the design detailed so that duplication of the study is possible? •Are the findings clearly described and reported? •Are the findings presented clearly and objectively? •Can the findings be enhanced with additional research? |
|
| Research method : |
Specific procedures used to gather and analyze research data. |
|
| Research methodology : |
Different approaches to systematic inquiry developed within a particular paradigm with associated epistemological assumptions (e.g. experimental research, grounded theory, ethno methodology). |
|
| Research problem : |
A formal statement of question or hypothesis that implies empirical investigation. |
|
| Research question : |
A clear statement in the form of a question of the specific issue that a researcher wishes to answer in order to address a research problem. A research problem is an issue that lends itself to systematic investigation through research. |
|
| Sample : |
The group of subjects from which data are collected. In other words, the group of people who participate in the study and whose data is used by the researcher. |
|
| Social research : |
Uses the same techniques as market research, but focuses less on business and more on public issues. See also audience research. |
|
| Statistical significant : |
A research term used to indicate whether the results from a study are very probably not due to chance. Take, for example, a study that reports it found that student test scores improved after a reading intervention program was initiated at a school, and that these findings are "statistically significant." That means that the researcher is reasonably certain that student test scores did actually improve over time. If research findings are not statistically significant, any increase reported may be due to chance, rather than a result of the intervention. |
|
| Survey Research : |
This is the systematic gathering of information about individuals and collectivities, using interview, questionnaire or response methods to elicit information directly, and interpreting the resulting data by means of statistical analysis. It provides and alternative to the experimental method or participant observation and is widely used in both qualitative and quantitative research. |
|
| Syndicated research : |
Research originated by a research company, with data sold to anybody who is interested - unlike an ad hoc survey, which is a one-off survey for an individual client. |
|
| Systematic methods : |
Data collection methods that are consistent and scientific-i.e. that follows the scientific method, used for collecting observations. |
|
| Theory : |
In its most general sense a theory describes or explains something. Often it is the answer to 'what', 'when', 'how' or 'why' questions. |
|
| Variable : |
An attribute or characteristics of a person or an object that takes on different values (i.e. that varies) within the population under investigation (e.g. age, weight, pulse rate). |
|
| Variance : |
A measure of dispersion or variability (spread), calculated by squaring the value of the standard deviation. |
