What is “Naturalism”?
How does it relate to “Validity”?
Naturalism is “the style of research that seeks to minimize the use of artificial methods of data collection” (p.28).
…or “a style of research designed to minimize disturbance to the natural or everyday social world” (p.402).
Naturalism relates to external validity in that “qualitative research tends…to take a naturalistic stance” (p.28).
True or False: Testability is a criterion of trustworthiness, as defined by Lincoln and Guba (1985).
To what do Lincoln and Guba’s criteria relate?
False.
The criteria of trustworthiness, according to Lincoln and Guba (1985), are:
- Credibility
- Transferability
- Dependability
- Confirmability
They recommend trustworthiness be the benchmark for the quality of a qualitative study because “some researchers argue that it is inappropriate to apply the concepts of reliability and validity to their research” (p. 29).
The main problem with cross-sectional design is that ________.
… it may be difficult to establish causal relationship from the data.
The nomothetic explanation of social activity might also be referred to as what explanation? What does it require?
The nomothetic explanation might also be referred to as “cause and effect.”
It requires correlation.
If a conclusion meets the criterion of internal validity what is reasonably certain?
A causal relationship between the variables is reasonably certain.
What are the types of validity?
Measurement (or construct) validity
Internal validity
External validity
With respect to cross-sectional designs, what can a longitudinal design overcome?
A longitudinal design overcomes the “direction of causation” problem found in cross-sectional design.
In what type of research is experimental design commonly used?
Quantitative.
What is the main significance of experimental design?
The main significance of experimental design is the logic of comparison it demonstrates.
What is a key component of validating cross-sectional research methodology?
Random sampling.
True or False: A case study research project may include data collection from multiple cases.
True.
True or False: Each type of research design has its qualitative and quantitative manifestation.
True.
With respect to tests, what does the classic experimental design requires?
A pre-test and post-test.
