Trait
Any distinguishable, relatively enduring way in which one individual varies from another
States
Any distinguishable, relatively enduring way in which one individual varies from another but less enduring that Traits
Sensation Seeking
the need for varied, novel, and complex sensations and experiences and the willingness to take physical and social risks for the sake of such experiences.
Cumulative Scoring
Inherent in cumulative scoring is the assumption that the more the testtaker responds in a particular direction as keyed by the test manual as correct or consistent with a particular trait, the higher that testtaker is presumed to be on the targeted ability or trait.
Error
Long-standing assumption that factors other than what a test attempts to measure will influence performance on a test.
Error Variance
The component of a test score attributable to sources other than the trait or ability measured.
Classical Test Theory (CTT) or true score theory
The assumption is made than each test-taker has a true score on a test that would be obtained but for the action of measurement error.
Psychometric Soundness
Reliability and Validity.
Reliability
The consistency of the measuring tool.
Validity
A test is considered valid for a particular purpose if it does, in fact, measure what it purports to measure.
Norms
Also referred to as normative data, norms provide a standard with which the results of measurement can be compared.
Norm
behaviour that is usual, average, normal, standard, expected or typical.
Normative Sample
Is that group of people whose performance on a particular test is analyzed for reference in evaluating the performance of individual testtatkers
to norm or norming
The process of deriving norms.
Standardisation or Test Standardisation
The process of administering a test to a representative sample of testtakers for the purpose of establishing norms.
Sampling
The process of selecting the portion of the universe deemed to be representative of the whole population is referred to as Sampling.
Sample
a portion of the univese of people deemed to be representative of the whole population.
Stratified Sampling
The process of inlcuding everyone in your representative population. i.e. All religions, races etc included in the Manhattan area.
Stratified Random Sampling
If everyone in the sample has the same chance of being included.
Standard Error of measurement
A statistic used to estimate the extent to which an observed score deviates from a true score.
Standard Error of Estimate
In regression, an estimate of the degree of error involved in predicting the value of one variable from another
Standard Error of the mean
A measure of Sampling Error
Standard Error of Difference
A statistic used to estimate how large a difference between two scores should be before the difference is considered statistically significant.
Purposive Sampling
Arbitrarily selected sample based on representativeness of the population.
