Reliability
|
Can be defined as the degree to which an obtained measure represents the true level of the trait being measured.
|
|
|
Test-Retest Reliability
|
A common procedure is to repeat a measurement over time. If the two tests are highly correlated the resulting measure is said to have high test-retest reliability.
|
|
|
Inter-Rater Reliability
|
When different observers agree with each other, the measure is said to have high inter-rater reliability.
|
|
|
Response Sets
|
Refers to the tendency of some people to respond to the questions on a basis that is unrelated to the questions content.
|
|
|
Extreme Responding
|
Refers to the tendency to give endpoint responses, such as "strongly agree" or "strongly disagree" and to avoid the middle part of response scales.
|
|
|
Social Desirability
|
Refers to the tendency to answer items in such a way as to come across as socially attractive or likable.
|
|
|
Validity
|
Refers to the extent to which a test measures what it claims to measure.
|
|
|
Face Validity
|
Refers to whether a test, on the surface, appears to measure what it is supposed to measure.
|
|
|
Predictive/Criterion Validity
|
Refers to whether the test predicts criteria external to the test.
|
|
|
Convergent Validity
|
Refers to whether a test correlates with other measures that it should correlate with.
|
|
|
Discriminant Validity
|
refers to what a measure should not correlate with.
|
|
|
Construct Validity
|
Defined as a test that measures what it claims to measure, correlates with what it is supposed to correlate with, and does not correlate with what it is not supposed to correlate with.
|
|
|
Generalizability
|
The degree to which the measure retains its validity across various context
|
|
|
Internal Consistency Reliability
|
If the items within a test viewed as a form of repeated measurement all correlate well with each other, then the scale is said to have high internal consistency reliability.
