1.
Reliability refers to the results obtained with an evaluation instrument and
not to the instrument itself.
2.
Reliability refers to a type of consistency.
3.
Reliability is a necessary but not a sufficient condition for validity.
4.
Reliability merely provides the consistency that makes validity possible.
5-
Reliability is a property of the assessment results rather than the property of
the instrument.
6-
It is more appropriate to speak of the reliability of assessment scores rather
than the reliability of an assessment.
7-
Reliability refers to the results (scores) of a test; not the test itself.
8-
An estimate of reliability refers to a particular type of consistency.
·
Consistency over
time. or,
·
Consistency
among raters. or,
·
Consistency of
performance across tasks.
·
Must have
reliability to have validity.
9-
A test can measure the same attribute with perfect consistency and not be
valid.
10-
Reliability is primarily statistical.
·
When estimating
reliability, we are trying to determine how much measurement error is present;
the less error, the more reliable the instrument.
