PSYC4022 Testing and Assessment Week One Gathering Information Flashcards
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.
Incidental Sampling/ Convenience Sampling
A sample based on the greatest level of convenience.
Percentile
The percentage of people who fall below a particular raw score.
Percentage Correct
The distribution of raw scores - the number of items answered correct multiplied by 100 and divided by the total number of items.
Age Norms/ Age-Equivalent Scores
Indicate the average performance of different samples of testtakers who were at various ages at the time the test was administered
Grade Norms
Are developed by administering the test to representative samples of children over a range of consecutive grade levels.
Developmental Norms
Age or Grade Norms which develop, deteriorate or otherwise be affected by chronological age, school grade or stage of life.
National Norms
are derived from a normative sample that was natioanlly representative of the population at the time the norming study was conducted.
National Anchor Norms
You can anchor the scores on one test against the scores on another test.
Equipercentile Method
the equivalency of scores on different tests is calculated with reference to corresponding percentile scores.
Subgroup Norms
Segmentation of the normative sample.
Local Norms
Provide normative information with respect to the local population’s performance on some test.
Fixed Reference Group Scoring System
The distribution of scores from one group of testtakers (the fixed reference group) is used as the basis for the calculation of test scores on future administrations of the test.
Norm Referenced
When you compare scores on a test to other scores on that test.
Criterion Referenced Evaluation
When you compare scores to some other criterion.
