FORMULATING HYPOTHESIS Flashcards
must be a controlled procedure
INTERNAL VALIDITY
presence vs absence
amount or degree
category
LEVEL OF IV
CONFOUNDING
problem if there is no random assignment
observable operation, procedures, measurements in context of an experiment.
OPERATIONAL DEFINITION
CONCEPTUAL DEFINITION
definition of the cited info
explains the precise meaning of IV; describe exactly what was done to create various treatment conditions of experiment.
EXPERIMENTAL OPERATIONAL DEFINITION
unseen processes to explain behavior; provided definitions involving variables that can be observed.
HYPOTHETICAL CONSTRUCTS
agreement between measurements of same responses from different observers.
INTERRATER RELIABITY
comparison of scores who have been measured twice with the same instrument.
TEST - RETEST REALIABITY
measures internal consistency; measures single construct variable
INTERITEM RELIABILITY
actually studying the variables that we intend to study.
VALIDITY
provides evidence to validity of an experimental procedure
MANIPULATION CHECK
measure what it intends to measure
FACE VALIDITY
how content of our measure fairly reflect the content of the quality we are measuring
CONTENT VALIDITY
ability of the instrument to predict future behavior based on the score they obtained.
PREDICTIVE VALIDITY
whether scores on a measuring device correlate with scores obtained from another method.
CONCURRENT VALIDITY
transition from theory to research application
CONSTRUCT VALIDITY
test result should highly correlate with scores on tests measuring same construct
CONVERGENT VALIDITY
test result should not highly correlate with scores on tests measuring other constructs.
DISCRIMINANT VALIDITY
type of prob in internal validity wherein factors that are note the focus of the expe can influence the findings?
EXGTRANEOUS VARIABLES
type of prob in internal validity wherein it sabotages an experiment, ext. variable changes systematically across diff conditions of expe
CONFOUNDING
proposed by Donald Campbell; all quasi-experimental studies contain one or more classic threats
CLASSIC THREATS TO INTERNAL VALIDITY
type of threat where it involves an outside event that happened before the experimentation; which can cause the experimental effects.
HISTORY
internal changes in subjects; studies that take months/ yrs to finish
