Terms | Definitions |
|---|---|
 Alternate-form Reliability | When the correlation coefficient is again used to asses the reliability of the set of scores |
| Concurrent Validity | Correlates with outcomes happening at the same time. Subcategory of Criterion Validity |
| Convergent Validity | Correlates with other similar measures. Subcategory of Construct Validity |
| Criterion Validity | Correlates with appropriate outcomes |
| Discriminant Validity | Testing for distinctiveness between measures or manipulations of related but conceptually different traits or behaviors. |
| External Validity | Conclusions made about the extent to which a casual relationship holds across variations in persons, settings, treatments and outcomes |
| Face Validity | "Makes sense" or Common sense test. |
| Internal-consistency Reliability | Checks for interrelated items, similar responses, and making sure they tap from the same construct |
| Internal Validity | Whether the observed covariation between variables truly reflects a relationship between the variables. |
| Plausible Rival Hypothesis | A competing explanation for results |
| Predictive Validity | Measured at two different times to predict the future. Subcategory of Criterion Validity |
| Random Error | Inaccuracies occurring by chance |
| Reliability | Measures are consistent or stable |
| Systematic Error | Fluctuations that are slanted in a particular direction; bias |
| Test-retest Reliability | For stable characteristics and a good test, a person should get the same scores on different occasions. |
| Validity | Truth or accuracy, how well a measure assesses what is purports to measure |
| Reliability-Validity Rule | You can have reliability without validity but not validity without reliability |
| Content Validity | Adequate coverage of areas. Generating more ideas than needed, omitting those that are not accurate. Representing the ideas they are supposed to represent |
| Construct validity | Meaning fits goal. Operational definition is accurate. |
| Cronbach's Alpha | Used to measure the reliability of a psychometric test score for a sample of examinees. |
