Q

Does the measure that is employed to measure a behaviour actually measure the behaviour is an example of…

A

Construct validity

16
Q

Examples of construct validity…

A

A measure of intelligence…through an IQ test

17
Q

Nomological network is a network of

A

Evidence surrounding and supporting the validity of a construct

18
Q

Nomological networks refers to a network of

A

Correlations which support NOT prove a construct

19
Q

The larger the nomological network for a construct the greater

A

The validity

20
Q

How many ways can we evaluate the viability of a scale in terms of construct validity?

A

Two

21
Q

What do both ways of evaluating the viability of a scale in construct validity assume?

A

That there is already a good measure of the construct available

22
Q

Two ways to evaluate the viability of a scale in terms of construct validity

A

Convergent validity

Discriminant validity

23
Q

Convergent validity is where our

A

Questionnaire that converges with other questionnaires that measure the same/related constructs. Should correlate

24
Q

Discriminant validity

A

A questionnaire should not correlate with questionnaires that measure different/unrelated constructs ie depression and anxiety

25
Q

Face validity

A

What it looks like. Does it seem sensible. Ie items relating to your construct.

26
Q

Content validity

A

Items on questionnaire judged to be appropriate by experts in the field

27
Q

Population validity

A

Extent to which results found in a sample can be generalised to a population.

28
Q

Criterion validity

A

Extent to which scores in a test are related to criterion validity

29
Q

Predictive validity

A

Shown when a questionnaire predicts another variable ie high GPA predicts honours performance

30
Q

Concurrent validity

A

Demonstrated by high correlation between 2 tests taken at the sane time. Assumes another questionnaire exists that us the gold standard for measuring that construct

31
