Norms Flashcards
a method of evaluation and a
way of deriving meaning from test scores by evaluating an individual testtaker’s score and
comparing it to scores of a group of testtakers.
the meaning of an individual
test score is understood relative to other scores on the same test.
norm-referenced testing and assessment
goal of norm-referenced
tests is
to yield information on a testtaker’s standing or ranking relative to some comparison
group of testtakers.
behavior that is usual,
average, normal, standard, expected, or typical.
Norm
are the test
performance data of a particular group of testtakers that are designed for use as a reference
when evaluating or interpreting individual test scores.
norms
definition, “particular
group of testtakers”
broadly (e.g., “a sample representative of the adult population of the United States”) or narrowly (e.g., “female inpatients at the Bronx Community
Hospital with a primary diagnosis of depression”)
group of people
whose performance on a particular test is analyzed for reference in evaluating the performance
of individual testtakers.
normative sample
verb to norm
the process of
deriving norms.
modified to describe a particular type of norm derivation: race norming
norming
the controversial practice of norming on the basis of race or
ethnic background.
race norming
consist of descriptive statistics
based on a group of testtakers in a given period of time rather than norms obtained by formal
sampling methods
user norms or program norms
The process of administering a test to a representative sample of testtakers for the purpose of
establishing norms
standardization or test standardization.
it has clearly specified
procedures for administration and scoring, typically including normative data.
standardized
To understand
how norms are derived, an understanding of ____ is necessary
sampling
process of developing a test, a test developer has targeted some defined
group as the population for which the test is designed.
Sampling
the complete universe
or set of individuals with at least one common, observable characteristic.
population
tests that have clearly
specified procedures for administration, scoring, and
interpretation in addition to norms.
standardized test
Type of “Standard Error”
Standard error of measurement
Standard error of estimate
Standard error of the mean
Standard error of the difference
statistic used to estimate the extent to which an observed score
deviates from a true score
Standard error of measurement
an estimate of the degree of error involved in predicting
the value of one variable from anothe
Standard error of estimate
A measure of sampling error
Standard error of the mean
statistic used to estimate how large a difference between two scores
should be before the difference is considered statistically significant
Standard error of the difference
portion of the universe of people deemed to be representative
of the whole population
sample
sample of the population
process of selecting the portion of the universe deemed to be
representative of the whole population
sampling
sampling
stratified sampling
stratified-random sampling
help prevent sampling bias and ultimately aid in the interpretation of the findings.
stratified sampling
If such
sampling were random (or, if every member of the population had the same chance of being
included in the sample), then the procedure would be
stratified-random sampling
