advantages and disadvantages of quota sampling
YAY:
- can control for characteristics you want
- cheaper
- fast
YUCK:
- not representative
- impossible to assess error
- biased
when to use quota sampling?
allows researchers to sample a subgroup that is of interest to their
study
a robust sample is
large enough to represent the population
but small enough to be measured easily and economically
for quantitative, n must be
at least 30-35
The problem with ordinal measures like surveys and self-reporting
Likely to have LOWER face validity because of poor operational
definitions
,"Did your food arrive promptly" - "promptly" may have different
meanings to Karen, who lives in The Woodlands and has the "Can I
Speak To Your Manager" haircut, than it does to Brianne, who worked
table service through eight years of college.
Longitudinal vs cross section
longitudinal >= 6 months
correlational research
explores correlations without intervention
correlation
a bond or association between 2 variables
a change in one means a change in the other
descriptive research
- often phenomenological
- goal is accurate picture of characteristics or circumstances
crossover design
group of subjects exposed to more than one condition or treatment
eg classroom cookie experiment
subjects serve as own controls
the capacity to detect true relationships is?
statistical power
the gold standard for intervention studies is
the RCT
counterfactual
,"what if..."
speculative bc we don't have time machines
eligibility criteria include
inclusion criteria - eg all participants have to have HTN
exclusion criteria - eg participants may NOT also have DM
purposive sampling
people are hand-picked based on researcher's knowledge
eg people who lost homes to Harvey
- obviously not probability/unbiased, but people who didn't go through
Harvey will not have any useful data.
sample size needs can be determined via
power analysis
an example of a visual analog scale is
the FACES pain scale
visual analogs are how long?
100mm
apparently it's a rule
IDK
advantages of questionnaires
advantages of interviews
Q: cheaper, anonymous
I: higher response rates, wider variety of participants (not everyone can
read, get to post office, has Internet, etc)
, biophysiologic measures include
VS, blood draws
in vivo, in vitro?
in vivo - in/on living organism (taking BP, ECG)
in vitro - outside organism (blood culture)
("vivo" should be obvious to anyone who speaks a Latinate language;
"vitro" is from Latin for "glass," referring to test tubes and such)
what's awesome about biophysiologic measures
objective
accurate
precise
assuming you know how to perform and interpret them
ethnonursing research focuses on
a group's beliefs and practices r/t nursing and health behaviors
basic social process
central social process that emerges through analysis of grounded
theory data
bracketing
(descriptive phenomenological) identifying and holding back opinions
about the phenomenon under study
case study
thorough in-depth analysis of person/group/social unit
constant comparison
