Psychometrics Chapter 1 /87 Questions With CompleteSolutions (A+)
Quiz :measurement - √Answer :at the heart of any research process in
psychology, education, or any other behavioural science; crucial to the study of
differences; purpose of measurement in psychology is to identify and quantify
the psychological differences that exist between people over time or across
conditions; if something is not measured, or it is not measured well, then it
cannot be studied with scientific validity; meaningful + accurate interpretation
of research findings = critical evaluations of measurements collected;
consequences of psychological measurement affect almost everyone, either
directly or indirectly; often involves making inferences about unobservable
events, things, and processes based on observable events
Quiz :instruments - √Answer :used to measure observable events in the
physical world (e.g. length = tape measure); used to measure properties of the
physical world that aren't directly observable (e.g. time = clock, voltmeters =
change in voltage); psychologists and educators use psychological tests as
instruments to measure observable events in the physical world (e.g.
behaviour)
, Quiz :behavioural scientists - √Answer :can use behaviour as a way of
assessing unobservable psychological attributes, such as intelligence,
depression, knowledge, ability, etc.
Quiz :observable behaviours - √Answer :measured to represent an
unobservable psychological attribute, state, or process; interpret
measurements in terms of the unobservable psychological characteristics;
conclusions drawn from the use of observable behaviour to measure
unobservable psychological characteristics requires the inference that the
observable behaviour (e.g. recalling digit strings) is systematically related to
the unobservable mental attribute (e.g. working memory); for the
interpretation of the observable behaviour scores to be considered valid, the
behaviour task must be theoretically linked to the unobservable psychological
characteristic
Quiz :psychological tests - √Answer :"a systematic procedure for comparing
the behaviour of 2 or more people"; often developed to sample behaviour
psychologists believe reflects the underlying psychological attribute, and
behavioural samples must be collected in a systematic way; measure
observable events in the physical world; conclusions drawn from the use of
observable behaviour to measure unobservable psychological characteristics
requires the inference that the observable behaviour (e.g. recalling digit
strings) is systematically related to the unobservable mental attribute (e.g.
working memory); purpose is to compare the behaviours of 2+ people, or
comparison of the same people at different points in time
Quiz :inference - √Answer :observable behaviour (e.g. recalling digit strings) is
systematically related to the unobservable mental attribute (e.g. working
memory); if the inference is reasonable, then our interpretation of the
behaviour has a degree of validity; for the interpretation of the observable
behaviour scores to be considered valid, the behaviour task must be
theoretically linked to the unobservable psychological characteristic
Quiz :validity - √Answer :scores from a measure actually measure the mental
state or process that we think they are measuring; we have validity if our
inference the observable behaviour to measures unobservable psychological
characteristics is reasonable
Quiz :theory - √Answer :often links psychological characteristics, processes,
or states to an observable behaviour that is thought to reflect differences in
