Standardized Tests & Testing Bias
Question | Answer |
---|---|
A test which is administered according to the same rules each time: | standardized test |
A standardized test has scores which are... | tabulated the same way each time |
Standardized tests yield scores that are usually reported as "standard scores", such as... | z scores, T scores, Normal Curve Equivalent (NCE) scores, Stanines |
Standard scores have equal... | intervals between scores |
These standard scores have a mean of zero and a standard deviation of 1.0 | z scores |
These standard scores have a mean = 50 and a standard deviation of 10 | T scores |
These standard scores have a mean = 50 and a standard deviation of 21.06 | Normal Curve Equivalent (NCE) scores |
Rather than discrete points, Stanines are interval scores. Each interval is... | 1/2 standard deviation |
Allows meaningful comparisons of scores from dissimilar geog. areas, everyone expected to have taken test under similar circumstances | common administration, tabulation, and reporting |
What does common administration, tabulation, and reporting allow for? | easy interpretation of the standard scores |
When there are systematic differences in scoring for reasons unrelated to learners' grasp of the construct measured there exists: | testing bias |
Consistent differences between group A and Group B... | do not necessarily constitute bias (they might occur for a variety of reasons) |
Testing bias: differences must be shown not to reflect... | actual differences in learners' knowledge |
