Methodologic challenges to research
Give this one a try later!
Major challenges are designing studies that are reliable and valid
(quantitative studies) as well as trustworthy (qualitative)
Gain entrée
,Give this one a try later!
Occurs in the early phases of a qualitative study; typically involves enlisting
the cooperation of gatekeepers or stakeholders within the study site
Describe the analytic phase (phase 4) of the quantitative research process
Give this one a try later!
Analyzing the data & interpreting results
Null hypothesis
Give this one a try later!
Expresses the absence of any relationship
Cross-sectional vs. longitudinal designs
Give this one a try later!
Cross-sectional involves the collection of data at one time period;
longitudinal designs involve data collection two or more times over an
extended period.
Positivist Paradigm
, Give this one a try later!
Reality exists; driven by natural causes. Inquirer is independent of research.
Values & biases held in check. Discrete, specific concepts. Fixed design and
tight controls over context. Measured, quantitative information. Deductive
processes - generalizations.
Casual vs. functional relationship
Give this one a try later!
Casual - cause and effect (ex., smoking and lung cancer)
Functional - association (ex., gender and life expectancy)
Dimensions/measure of trustworthiness in qualitative studies (4)
Give this one a try later!
Credibility, confirmability, dependability, tranferability
Describe the second stage in qualitative research: conducting the study
Give this one a try later!
Making sampling decisions, collecting data, evaluating trustworthiness,
analyzing data, interpreting data
