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 AO3 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.
