Unit 4 Flashcards
any distinguishable, relatively enduring way in
which one individual varies from another
trait
The trait term an observer applies, as well as the
strength or magnitude of the trait presumed to be
present, is based on observing a
sample of behavior
also distinguish one person from another but
are relatively less enduring
states
a psychological trait exists only as a -
construct
We can infer the existence of psychological traits from -
overt behavior
Whether a trait manifests itself in observable behavior,
and to what degree it manifests, is presumed to
depend not only on the strength of the trait in the
individual but also on the
nature of the situation
The test score is presumed to represent the strength
of the targeted ability or trait or state and is frequently
based on
cumulative scoring
Refers to a long-standing assumption that factors
other than what a test attempts to measure will
influence performance on the test
error
The component of a test score attributable to
sources other than the trait or ability measured
error variance
Potential sources of error variance:
(1) Assessees and assessors
(2) Measuring instruments
(3) Random, or just a matter of chance
What error?
present in all test takers because they will all experience it
systematic error
What error?
may be environmental, only a few test takers will experience it
random error
What error?
instruments used have an error or inaccurate (e.g. weighing scale ^^)
instrumental error
What error?
when different procedures are used to answer the same questions provides slightly different answers
procedural error
characteristics of a psychological test
objectivity
standardization
reliability
validity
utility
what characteristic of a test is this?
a degree to which equally competent scores obtain the same results
objectivity
what characteristic of a test is this?
a test is made uniform or set to adhere to a specific standard
involve administering & scoring in the same way for everyone that takes the test
standardization
what characteristic of a test is this?
how accurate the test is, and if it measures what it intends to measure
validiy
what characteristic of a test is this?
usefulness of a particular test
utility
what characteristic of a test is this?
how reliable the test is, especially if you administer it multiple times
reliability
A method of evaluation and a way of deriving
meaning from test scores by evaluating an
individual testtaker’s score and comparing it to
scores of a group of testtakers
Norm-referenced testing and assessment
