| Validity is the _______________ that we can attach to a score | meaning |
| What type of simple validity test is this? "correlation between a score and a criterion score - comparing scores of new measure with scores of old measure and seeing if they correlate" | Concurrent validity |
| Do we use test-retest to test for the reliability of Assessment episode of Raters and Interviewers? | Assessment episodes |
| To test the reliability of Raters and interviewers we can use the ________________ test | inter-rater |
