Cards

Term
Generalization
Definition
the application of information to a general situation that has been acquired from a specific instance (research study).
Term
dependent variable
Definition
outcome or the presumed effect that varies with a change in the independent variable
Term
emic view
Definition
view of the person experiencing the phenomenon that reflects his/her culture, values, beliefs, and experiences
Term
Qualitative studies involve
Definition
Understanding the meaning of a human experience such as grief, hope, or loss
Term
Review of literature
Definition
an organized critique of the scholarly literature that supports a study.
Term
Key informants
Definition
Individuals who have special knowledge, status, or communication skills and who are willing to teach about the phenomenon
Term
Does a fully developed research question always have a clear answer?
Definition
NO
Term
purpose
Definition
the aims or goals the investigator hopes to achieve with the research
Term
3 parts of a true experimental design
Definition
randomization, control, manipulation
Term
outcome you are trying to measure
Definition
dependent variable
Term
quantitative research
Definition
Describes new situations, events, or concepts
Term
4 types of quantitative research
Definition
-Descriptive
-Correlational
-quasi-experimental
-Experimental
Term
When is descriptive research conducted?
Definition
when there isn't enough info on how often, if, or to what extent something occurs
Term
descriptive research
Definition
-Exploration and description of phenomena in real-life situations
-New meaning is discovered and the description of concepts is accomplished
-It helps to identify relationships
Term
What does correlational research test?
Definition
the strength of the statistical relationship between or among variables, usually as they exist in a natural setting, not a research lab. Variables are measured, and then calculations are performed to demonstrate whether variables are correlated and how strong that relationship is
Term
Correlational research
Definition
-looks at the relationship between 2 or more variables
-explains what is seen
-NO CAUSE AND EFFECT
-determines strength/type of relationship
Term
quasi-experimental research
Definition
-cause and effect relationships
-less control than experimental
-samples not randomly selected
-all variables cannot be controlled
Term
What do quasi-experimental studies lack that experimental studies have?
Definition
-a control group that is distinct and separate from the experimental group
-randomly assigned subjects to either treatment or control group
Term
True or false: quasi-experimental research looks like experimental search but lacks randomly assigned control group
Definition
TRUE
Term
Experimental research
Definition
-looks at cause and effect relationships
-highly controlled
-involves measurement of independent and dependent variables
Term
3 things common to all experimental studies
Definition
-control group
-randomly assigned subjects
-intervention to only experimental group
Term
gold standard of research designs
Definition
randomized controlled trial
Term
True or false: Experimental studies have controlled manipulation of at least one independent variable
Definition
TRUE
Term
case control study
Definition
people with a disease are matched with people who do not have the disease (look for other characteristics as well- such as hx of smoking)
Term
Retrospective study
Definition
looks back in time
Term
prospective study
Definition
looks forward in time
Term
Cohort study
Definition
-prospective
-subjects who presently have a certain condition and/or receive a particular treatment are followed over time and compared with another group who are not affected by the condition
Term
Cross sectional study
Definition
exposure and outcome are evaluated at the same time
Term
longitudinal study
Definition
-prospective
-collection of data at multiple time points
-repeated observations of same data over long periods of time
Term
applied research
Definition
Knowledge applied directly in the actual setting in which the study was conducted
Term
rigor
Definition
Striving for excellence in research and adherence to detail
Term
random assignment
Definition
the process of assigning subjects to either experimental or control group
Term
random selection
Definition
the process of selecting the total sample from a larger population (ex: selecting only every third person who comes into an emergency room)
Term
Extraneous variables
Definition
-occur in all research studies
-may interfere with the stated relationships between variables
-can be decreased through sample selection and the use of defined research settings
Term
pilot studies
Definition
Studies with small sample sizes often done to test the feasibility of the intervention that will be used in a larger follow up study
Term
qualitative research
Definition
-describe life experiences and give them meaning
-narrative that describes what is happening
Term
qualitative research data is
Definition
subjective
Term
5 approaches to qualitative research
Definition
-phenomenology
-grounded theory
-ethnographic
-historical research
-case study
Term
phenomenology
Definition
Purpose is to describe and capture the “lived experience” of study participants
Term
hermenuetics
Definition
-uses textual analysis
-exposes hidden meanings
-helps to understand human nature
-based on heidiggers philosophy
Term
grounded theory is based on
Definition
symbolic interaction theory
Term
grounded theory is similar to
Definition
phenomenology
Term
grounded theory explores
Definition
how people define reality and how their beliefs are related to their actions
Term
symbolic interactionism
Definition
humans who interact with one another over time develop certain shared meanings represented as symbols, which represent common thoughts, beliefs, and values
Term
ethnographic research
Definition
-for studying cultures
-seeks to understand people's beliefs, ways of living, etc.
Term
emic approach
Definition
study from within a culture
Term
etic approach
Definition
study from outside the culture
Term
historical research is based on
Definition
events from the past
Term
Case study
Definition
narrative report of one or more research subjects or families in a given setting
Term
research problem
Definition
Area of concern; gap in knowledge needed for practice
Term
research purpose
Definition
-Goal, aim, focus, or objective of study
-Includes variables, population, and setting
Term
research questions
Definition
interrogative statements that focus on what variables or concepts are to be described and what relationships might exist among them
Term
associative hypotheses
Definition
Relationship between variables
Term
causal hypotheses
Definition
cause and effect relationship between variables
Term
simple hypotheses
Definition
two variables
Term
complex hypotheses
Definition
two or more variables
Term
non directional hypotheses
Definition
Relationship exists between variables, but hypothesis does not predict nature of relationship
Term
directional hypotheses
Definition
Nature (positive or negative) of interaction between two or more variables is stated
Term
null hypotheses
Definition
States there is no difference or relationship between variables
Term
research hypotheses
Definition
-States what researcher thinks is true
-There is a relationship between two or more variables
Term
confounding variable
Definition
the variable is not recognized until the study is in process or cannot be controlled
Term
demographic variables
Definition
Contain sample characteristics of subjects
Term
conceptual definition
Definition
Abstract meaning of a variable that usually is based on theory
Term
operational definition
