Here is an example of a question you might be asked on this topic - for AO2 and AO3.
AO2: You need to apply your knowledge and understanding, usually referring to the ‘stem’ in order to do so (the stem is the example given before the question)
AO3: You need to analyse and evaluate key concepts, ideas, theories and research.
Professor R.E.Call runs an experiment which investigates how many items on a list participants can remember depending on whether they recall the list in silence or when music is playing.
Question: Explain what type of data (primary or secondary) has been collected by the professor. Outline one strength of this type of data. [2]
Model answer:
- The professor has collected primary data as he has run his own experiment i.e. it is data collected at source.
- One strength of primary data is that the researcher can exert full control over how it is collected which makes it more reliable than secondary data.
