1. G r a v e AO3 EVALUATE GENERALISABILITY VALIDITY
Can the results of the study be generalised to other types of people? If a study only uses students for example, we cannot generalise the findings to people who are not students e.g. full-time workers.
VALIDITY
This refers to the extent to which the test measures what it claims to measure.
Internal – does the test measure what it intended to or has other extraneous factors influencing?
External – looks at factors outside of the study. Who is the study meant to be representative of? Can it be generalised?
Ecological – does the task/experiment reflect that of real life?
Population - Is the sample representative of the wider target population of the study?
Face – does the test appear to test what it aims to test? (EG. Does IQ testing really measure intelligence?)
Construct – does the test relate to underlying theoretical concepts?
Concurrent – does the test relate to an already existing similar measurement?
Criterion – is the test/experiment made up of concurrent and predictive validity
One weakness of the study is that it lacks mundane realism…
State your point(D-C)
RELIABILITY
This refers to how controlled and consistent a study is.
Internal - Whether a procedure in a study can be replicated e.g. can the tools used to measure behaviour be used again?
External - The measures used to measure behaviour receive the same or similar results when replicated.
Inter-rater - Two or more individuals have a high agreement on a score and therefore the measurement of behaviour is reliable
This means that the task is not something you would carry out in everyday life…
Explain your point(C-B)
Use the train to expand your evaluation!
For example, it not a usual task to be asked to learn a list of words and then count back in threes…
Link your point(B-A)
APPLICATION
Can the study be applied to real life? What can we do with the results in a real-life setting?
Think bigger than the study – think worldwide

EVALUATE
Counter-argument(A*)
However, despite the study lacking mundane realism, it was carried out in a lab and therefore it has good control, and could be easily repeated.
