|
What is Reliability? |
How consistent/dependable a test and its results are. |
|
|
What is Internal Reliability? |
Its when different parts of the test should give consistent results. |
|
|
What is Split-half Reliability? |
A measure of reliability that measures two halves of a test. For example, odd and even numbers. (If both halves correlate well, the measure has good reliability). |
|
|
What is External Reliability? |
When the test should give consistent results regardless of when its used. |
|
|
What is Inter-rater Reliability? |
When the test should give consistent results no matter who does/administers it. |
|
|
What is Test Re-test Reliability? |
A measure f reliability that uses the same test twice. (If two sets of scores correlate well, the measure has good reliability). |
|
|
What is Validity? |
How well a test measures what it claims to. |
|
|
What is Internal Validity? |
The extent to which results of the test are caused by the variable being measured (DV), rather than extraneous variables. |
|
|
What is External Validity? |
The extent to which results can be generalised. |
|
|
What is Face Validity? |
It measures the test at face value, (measures what it claims to). |
|
|
What is Construct Validity? |
Whether the test is based on some certain-to-exist phenomenon. |
|
|
What is Population Validity? |
The extent to which findings can be generalised to the whole population from which the sample was taken. (If the participants of a sample were all American, this would reduce the population validity as they sample would have been ethnocentric). |
|
|
What ic Criterion Validity? |
Indicates whether a phenomenon measured in one way will relate to/predict some other related variable. |
|
|
What is Concurrent Validity? |
Whether a measure will produce similar scores for a particular individual as another test that claims to asses the same phenomenon. (This is a type of Criterion Validity). |
|
|
What is Ecological Validity? |
The extent to which the results reflect real life. |
