Mark scheme

Examiner's comment
Students generally understood the difference between primary and secondary data. Some were less adept at identifying the advantages of such data. Students who claimed that primary sources were more valid; reliable; representative were required to explain how this is the case to gain credit as such qualities could equally be a feature of secondary sources of data. More successful responses were able to use the fact that the researcher was in control over the entirety of the research process to formulate effective answers.
Notes from the mark scheme and report
- 2 marks for each of two advantages clearly outlined, 1 if partial (e.g. researcher gathers exactly what is needed, operationalises concepts their own way, knows how the data were produced, fills gaps where no secondary data exist)
- bare claims that primary data are more valid, reliable or representative need explaining, since secondary data can share these qualities
- best answers stressed the researcher's control of the whole process
