Q

What is face validity and what is an example of high face validity

A

Does the measure ‘appear’ to measure what it set out to.
Example = if someone looks happy then we might assume that happiness is their valid state

Q

What is construct validity and what is an example of high construct validity

A

Does the study measure the full range of components that make up a behaviour
Example = looking a body language, contentment and optimistic outlook not just a simile on their face when measuring happiness

Q

What is criterion validity and what are the 2 types of criterion validity

A

Does they measurement of a variable in one way relate to the measurement of the same variable but in a different way
Types= concurrent and predictive

Q

What is concurrent validity and what is an example of high concurrent validity

A

Does a new measurement or test measure the same thing as an old one that has already been validated.
Example = if someone passed on the old driving test then they should pass on the new one

Q

What is predictive validity and what is an example of high predictive validity

A

Does the measurement of a behaviour predict the performance on another related measurement.
Example = someone who performed very well in their GCSEs should also perform well in their alevels

Q

What is external validity

A

Can the findings be generalised beyond the sample. If you can then the study is externally valid.

Q

What is population validity and what is an example of low population validity

A

The extent to which finding can be generalised to the target population

Example= want to find out about all adults but only use 50 female psychology undergraduates

Q

What is ecological validity and what is an example of low ecological validity

A

The extent to which findings can be generalised to real life situations

Example = want to investigate the effect of something on driving but you use a driving simulator which is an artificial environment and doesn’t have the same surrounds as driving normally

Q

What is temporal validity and what is an example of low temporal validity

A

The extent to which findings can be generalised to different time periods.

Example = a study investigating attitudes towards tv adverts in the 70s and 80s may have very different findings to now due to media ads becoming more common. So previous study lack temporal validity

15
Q

What is internal reliability

A

How consistent the procedure is e.g. are all participants experiencing the same thing and being treated in the same way.

16
Q

How do we test for internal reliability

A

Split half method = spilt the test in half and compare the performance on one half with performance on the other half, a strong positive correlation indicates reliability.

Inter-rater reliability

17
Q

What is external reliability

A

If the procedure has been repeated are the results consistent is so then it has high external reliability

18
Q

How do we check for external reliability

A

Test-retest method = repeat the test on more than one occasion and compare performance on the test a strong positive correlation indicates reliability

19
Q

;how do you identify the level of internal validity in an experiment

A

What levels or control are there
Are participants aware

20
Q

how do you identify the level of external validity in an experiment

A

Where is the setting
What is the task

21
Q

how do you identify the level of internal reliability in an experiment

A

What level of control is there
Have all ppts had the same experience

22
Q

how do you identify the level of external reliability in an experiment

A

Has the procedure been repeated

23
Q

how do you identify the level of internal validity in an correlation

A

How have the variables been measured
Could there be other factors influencing the relationship
Are the measures being done in a controlled way

24
Q

how do you identify the level of internal reliability in an correlation

A

What level of control is there
Have all the ppts had the same measure

25
Q

how do you identify the level of external reliability in an correlation

A

Has the procedure been repeated is so did you get the same results

26
Q

how do you identify the level of internal validity in an observation

A

What level of control is there
Are participants aware that they are being observed
What observation schedule is being used
Are categories being used

27
Q

how do you identify the level of external validity in an observation

A

Where is the setting

28
Q

how do you identify the level of internal reliability in an observation

A

What level of control is there
Is there a structure to when you observe
Did you have inter rater reliability

29
Q

how do you identify the level of external reliability in an observation

A

Have you repeated the procedure if so did it have the same results

30
Q

how do you identify the level of internal validity in an self-report

A

What level of control is there
Is it confidential
Face to face or private
Are questions clear and operationalised

31
Q

how do you identify the level of internal reliability in an self-report

A

What level of control is there
Have all the ppts had the same experience
split half method
Repeat questions

32
Q

how do you identify the level of external reliability in an self-report

A

Re test method and did you get the same results
