Norm-referencing does not ensure that a test is valid (i.e. that it measures the construct it is intended to measure). Another disadvantage of norm-referenced tests is that they cannot measure progress of the population as a whole, only where individuals fall within the whole.
Test scores are interpreted with a norm-referenced or criterion-referenced interpretation, or occasionally both. A norm-referenced interpretation means that the score conveys meaning about the examinee with regards to their standing among other examinees. A criterion-referenced interpretation means that the score conveys information about the ...
Norm-referenced test Norm-referenced tests compare a student's performance against a national or other "norm" group. Only a certain percentage of test takers will get the best and worse scores. Norm-referencing is usually called grading on a curve when the comparison group is students in the same classroom. Norm-referenced tests report whether ...
A norm-referenced test may be designed to find where the test taker falls along a normal curve. A normative assessment compares each test-taker against other test-takers. A norm-referenced test (NRT) is a type of test, assessment, or evaluation which yields an estimate of the position of the tested individual in a predefined population. The ...
Most achievement tests are norm-referenced. The individual's responses are scored according to standardized protocols and the results can be compared to the results of a norming group. [1] Norm-referenced tests can be used to underline individual differences, that is to say, to compare each test-taker to every other test-taker.
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
While mean scores from Likert-type scales can be compared across individuals, scores from an ipsative measure cannot. To explain, if an individual was equally extraverted and conscientious and was assessed on a Likert-type scale, each trait would be evaluated singularly, i.e. respondents would see the item "I enjoy parties" and agree or disagree with it to whatever degree reflected their ...
In contrast, an example of a relative, or norm-referenced, decision would be when the individual's test score is used to either (a) determine relative standing as compared to his/her peers (i.e. a child's score on a reading subtest is used to determine which reading group he/she is placed in), or (b) make intra-individual comparisons (i.e ...
