Lecture 4.1 Flashcards
1
Q
defintion validity
A
- does the test measure all and nothing else
2
Q
face validity
A
- surface impression of examinee
3
Q
content validity
A
- does the test cover the whole contruct
4
Q
method of content validity
A
- panel of experts
- proportion of items that are deemed relevant
5
Q
criterion validity
A
- compared to external standard
6
Q
concurrent validity
A
- part of critirion validity
- e.g. a diagnosis
7
Q
predicitve validity
A
- prediction of future behavior
8
Q
requirements for critirion validity
A
- reliable
- free of contamination (overlap)
9
Q
decision theory
A
- hits = correct prediction
- false positive = flase alarm
- false negative = incorrectly classified
10
Q
sensitivity
A
- how well the test picks up real things
11
Q
specificty
A
- correct negative classifications
12
Q
convergent validity
A
- correlation with similar instrument
- part of construct validity
13
Q
multimethod
A
- different instruments to test
- assesses convergent validity
14
Q
multitrait
A
- correlation with unrelated tests
15
Q
multitrait-multimethod matrix
A
- table to asses correlation of convergent and discriminate validity
