What is test reliability?
What are the aspects of reliability that are most important for the teacher/tester?
The reliability of a measuring device is high when any variations in readings taken represent true difference between the individuals being tested. Any other variation represents error.
The reliability of a test is its consistency: tape measure that stays the same length all the time as opposed to a piece of elastic. Same results should be obtained wherever the tape measure is used.
Comparison with different tests: i.e. whether the students takes one version of the test e.g. CFE, or another, the result should be the same.
THREE ASPECTS OF RELIABILITY 1) Circumstances in which the test is taken 2) The way in which it is marked 3) the uniformity of assessment it makes.
EXTRINSIC sources of error: i) Examiner variability ii) Variability of testing conditions.
INTRINSIC sources i) Lack of stability ii) Lack of equivalence.
