Categorical variable Variables that take on a handful of discrete non quantitative values
Cause-and-effect relationship The causal relationship between two variables; ex: cigarette smoking and lung cancer
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

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
Setting The specific places were information is gathered
Site The overall location for the research
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
