100
A statement articulating the research problem and making an argument to conduct a new study
What is Problem statement
100
An abstract generalization that systematically explains relationships among phenomena
What is Classical Theory
100
Same people are compared at different times or under different conditions.
What is within-subjects design
100
The aggregate of cases in which a researcher is interested
What is Population
100
The assignment of numbers to represent the amount of an attribute present in an object or person, using specific rules
What is Measurement
200
The researcher’s predictions about relationships among variables
What is Hypotheses
200
Represents a more loosely structured attempt to explain phenomena than theories
What is a Model
200
From whom will critical information be withheld to avert bias
What is Masking/blinding
200
The systematic over- or underrepresentation of segments of the population on key variables when the sample is not representative
What is Sampling Bias
200
The score that would be obtained with an infallible measure
What is True Score
300
Identifies key study variables
What is Statement of Purpose
300
Human beings, Environment, Health & Nursing
What are the four concepts central to models of nursing
300
A research design that involves a nonrandomized controlled trial
What is quasi-experimental research design
300
Type of sampling that is most vulnerable to bias
What is Convenience sampling
300
The consistency and accuracy with which an instrument measures the target attribute
What is Reliability
400
Predicts the existence of a relationship, not its direction
What is Nondirectional hypothesis
400
Grounded, Ethnography & Phenomenology
What is Theories in Qualitative Research
400
Is what would have happened to the same people exposed to a “cause” if they simultaneously were not exposed to the cause
What is Counterfactual Model of Causality
400
Questions prespecified in written form, to be self-administered by respondents
What is a Questionnaire
400
The extent to which scores are similar on two separate administrations of an instrument
What is Stability
500
Expresses the absence of a relationship (used only in statistical testing)
What is Null
500
Using a theory/model as an organizing or interpretive structure
What is the Use of Theories or Models in Quantitative Research
500
Design that offers the strongest evidence of whether a cause (an intervention) results in an effect (a desired outcome).
What is Experimental Design
500
Used to make fine quantitative discriminations among people with different attitudes, perceptions, traits
What is Scales
500
Refers to whether the instrument looks as though it is an appropriate measure of the construct
What is Face Validity
