hi
3 methods of measurement
what is self report, observational, physiological?
protection against selection bias
what is randomization and matching?
concurrent measures design
what is when participants are exposed to all levels of the IV at the same time?
to avoid with self report
what is response sets and asking people more than what they know?
ethics of observation and recording
what is
deception
public behavior vs private
informed consent
ID'ing people?
the 4 scales of measurement
what are nominal/categorical, ordinal, interval, ratio
protection against experiment bias
what is keep experimenters blind and double blind experiments?
advantages of studies done within groups
what is they are their own control, greater power, need fewer participants
response sets
what is acquiescence, fence sitting, and faking good/bad?
types of samples
what is biased samples
unbiased samples
convenience sampling
self selected volunteers
what is test-retest, interrater, internal?
post test only design
what is a true experiment, a typical experiment?
disadvantages of within groups
what is when iv makes a lasting change, order effects, external validity issues, generalization problems?
aspects of observations
what is they are more difficult than surveys/polls/selfreports,
they might be more valid
dont need consent?
properties of surveys and observations
what is can be used to test frequency and sometimes association,
cannot show cause and effect,
present complicated technical and ethical questions?
what is face, content, criterion, convergent, and discriminant?
pre-post design
what is when all participants are given a pre test, treatment, and a post test?
4 effect validities
what is construct, external, statistical, internal validity?
avoid with observations
what is observer bias, observer effects, and participant reactivity?
types of random sampling
what is cluster/multistage
stratified
over
systematic?
what you focus on when measuring variables
what is scale, method, reliability, validity
problems with pre-post design
aspects of surveys and observations test
what is tests relationships and correlations,
frequency hypotheses or claims,
and sometimes association hypotheses or claims?
ways to score observed behavior
what is coding systems and interrated reliability?
types of nonrandom sampling
what is snowball,
convenience,
purposive,
quota?
