✔✔What do nonexperimental designs attempt to test (observe/analyze)? -
✔✔Differences among variables
✔✔Keywords for Descriptive Exploratory Designs: - ✔✔Characterization
✔✔When is a Descriptive Exploratory Design used? - ✔✔When little is known about a
research topic
✔✔Keywords for Correlational studies: - ✔✔Relationships
Variables
✔✔Are causal inferences/relationships are analyzed or made? - ✔✔Analyzed
✔✔Cross-Sectional studies involve data collection at one point / multiples points in
time? Does it allow multiple group comparisons? - ✔✔One point
Yes
✔✔Keywords for longitudinal/prospective studies: - ✔✔Observing change
Own controls
Trends in data
✔✔Key concepts for Ex Post Facto/Retrospective: - ✔✔the dependent variable has
already been affected.
offers a higher level of control than does a correlational study.
✔✔Psychometrics deal with (_) and delvelopment of (_)(_) - ✔✔Theory
Measurement instruments
, ✔✔Descriptive nonexperimental studies use what instead of hypotheses? -
✔✔Research Questions
✔✔Methodological studies (_) constructs/concepts? What is it design to test? -
✔✔Measures
New instrument/tool's validity & reliability
✔✔Survey designs explores what? - ✔✔variables
✔✔Studies that are considered as survey designs (3): - ✔✔Descriptive
Exploratory
Comparative
✔✔Relationship-Difference Studies include: - ✔✔Correlation
Developmental
Cross-sectional
✔✔Developmental studies include: - ✔✔Cross-sectional
Longitudinal
Prospective
Cohort
✔✔When would you not use survey designs? - ✔✔When information collected is
relatively superficial
✔✔Samples should explicitly describe the population criteria for what? - ✔✔Inclusion
eligibility
✔✔Clear eligibility criterias are designed to: - ✔✔Increase homogeneity of the sample
✔✔The Criterion for Representativeness when the sample closely resembles what? -
✔✔Larger target population
✔✔The sampling strategy at greatest risk for sample bias is convinience or purposive? -
✔✔Convinience
✔✔Quota vs Purposive Strategies: - ✔✔In quota sampling, the researcher ensures that
proportional segments of the population are included in the sample.
In purposive sampling, the researcher hand picks cases based on his or her knowledge
of the population (preterm infants).
