Here is an example of a question you might be asked on this topic - for AO2.
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)
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 why collecting quantitative data rather than qualitative data may increase the reliability of the data collected by the professor. [2]
Model answer:
- Recalling items on a list will generate quantitative data as the results will be measured as to how many items each participant could remember per condition.
- Using quantitative data as outlined above increases the reliability of the data collected as these responses can be translated into percentages, graphs etc. for easy comparison across conditions.
