| Co-investigator | An individual involved with the principal investigator and conducting the study |
| Collaborative research | Research that involves the cooperation of researchers, institutions, organizations and/or communities, each bringing distinct expertise to a study |
| Concept | abstractions, particular aspects of human behavior i.e. pain, quality of life, anxiety in QUANTITATIVE research |
| Conceptual definition | The abstract or theoretical meaning of a concept being studied; ex: studying arthritis pain in elderly men over age 70 |
| Conceptual models | Interrelated concepts or abstractions assembled in a rational and often explanatory scheme to illuminate relationships among them |
| Continuous variable | this type of variable has an infinite amt of values between 2 data points, values along a continuum |
| Data | The pieces of information obtained in a study |
| Data saturation | A principle used by qualitative researchers when themes & categories in the data become repetitive and redundant such that no new information can be gleaned by further data collection |
| Dependent variable | The presumed effect (of an independent variable) |
| Dichotomous variable | When categorical variables take on only two values; ex: male or female |
| Discrete variable | A variable that has a finite number of values between any two points |
| Ethnology | The study of the lifeways and experiences of a defined cultural group; these researchers strive to learn from members of a cultural group to understand their worldview and to describe the customs and norms |
| Extraneous variable | A variable that confounds the relationship, it is not the independent variable, but could affect the results of the experiment & therefore must be either in the research design or through statistical procedure |
| Framework | The conceptual underpinnings of a study based on a specific conceptual model |
| Generalizability | The inference that research findings can be generalized from the sample to a broader group or population outside the study |
| Grounded theory | a qualitative research theory tradition with roots in sociology that seeks to describe and understand the key social psychological processes that occur in a social setting |
| Heterogeneity | a type of group where an attribute is extremely varied in the group under study |
| Homogeneity | a type of group of which the amount of variability is limited; the degree to which the objects are similar |
| Hypothesis | A statement of the researcher's expectations or predictions about relationships among study variables |
| Independent variable | The presumed cause (of a dependent variable) |
| Informant | In a qualitative study these individuals of cooperating in the study they are also called informants |
| Investigation | a study; when researchers address a problem through research |
| Investigator | the person undertaking the study |
| Key informant | are those whose social positions in a research setting give them specialist knowledge about other people, processes or happenings that is more extensive, detailed or privileged than ordinary people, and who are therefore particularly valuable sources of i |
| Multisite study | The multiple locations in which the researchers do their study |
| Naturalistic setting | A setting for the collection of research date of it is natural to those being studied; ex:Homes places of work |
| Operational definition | The operations (measurements) a researcher must perform to collect the desired information; ex: how you're going to measure it- pain scale, physical testing |
| Outcome variable | Another term for dependent variable |
| Peer reviewer | People at a similar level of experience to the research ers called up on to give a critique on a study an offer feedback |
| Phenomena | abstractions, particular aspects of human behavior i.e. pain, quality of life, anxiety in QUALITATIVE research |
| Phenomenology | A qualitative research tradition concerned with the lived experiences of humans it's an approach to thinking about what life experiences of people are like and what they mean |
| Principal investigator (PI) | When a study is done by a team this person directs the study |
| Project director | |
| Qualitative data | Researcher information consisting of narrative descriptions |
| Quantitative data | Researcher information consisting of NUMERIC form |
| Researcher | the person undertaking the study |
| Respondent | Inner self report study the person responding to questions posed by the researcher |
| Reviewer | A person sometimes called on to critique a study in offer feedback |
| Sample | The collection of study participants in both a qualitative and quantitative study |
| Scientist | |
| Setting | The specific places were information is gathered |
| Site | The overall location for the research |
| Sponsor | |
| Study | When researchers address a problem through research |
| Study participants | In quantitative study these people are the ones being studied they are also called subjects |
| Subjects | In quantitative study these people are the ones being studied they are also called study participants |
| Systematic bias | An error in research that is consistent & distorts results in a single direction; it is more preferred then a random type; ex: a spring scale consistently measured people's weight as being 2 pounds heavier than their true weight |
| Theory | systematic, abstract explanation of some aspect of reality. concepts come together in a coherent system to explain some aspect. |
| Variability | The degree to which values on a set of scores are dispersed |
| Variable | a characteristic or quality that takes on different values; ex: something that varies or changes from one person to the next |
