|
|
Operational definitions
|
Define abstract constructs in term of specific procedures and measures.
|
|
Variables
|
Events, objects, people, or phenomena that vary in amount, degree, or kind with respect to certain aspects.
|
|
Experimentation
|
Involves active manipulation of variables by a researcher and control of environmental factors to exclude alternate explanations for the observed results.
|
|
Measurement
|
The assignment of numbers to aspects of events, objects, people, or phenomena according to a set of rules or conventions
|
|
Observed Score
|
Any score assigned to an attribute or characteristic of an individual through a measurement proecss; thought to be a combination of true scores and measurement error.
|
|
True score
|
The average score that an individual would earn on an infinite number of administrations of the same test or parallel versions of the same test.
|
|
Error Score or Measurement Error
|
The hypothetical difference betwen an observed score and a true score.
|
|
Random Errors
|
Errors that vary in unpredictable ways upon repeated measurement.
|
|
Measurement Scale
|
A set of rules by which numbers may be assigned to aspects of events, objects, people, or phenomena.
|
|
Reliability
|
The degree to which observed scores are free from random measurement errors; an indication of the stability or dependability of a set of measurements over repeated applications of the measurement procedure.
|
|
Systematic Errors
|
Errors that occur upon repeated measurements; also known as the occurence of bias in the measurements
|
|
Validity
|
The degree to which accumulated evidence and theory support specific interpretations of test scores in the context of the test's proposed use.
|
|
Validity Generalization
|
The application of validity evidence, obtained through meta analysis of data obtained from many situations, to other situations, which are similar to those on which the meta analysis is based.
|
|
Bias
|
Systematic errors in measurement, or inferences made from measruements, that are related to different identifiable group membership characteristics such as age, sex, or race.
|
|
Fairness
