Which of the following is not a source of primary data? Option (A) focus groups, option (B) personal investigation, option (C) telephone calls, option (D) questionnaires, or option (E) research journals and newspapers.

We can recall that we can categorize data into two different types. Primary data is new information which is collected and organized directly by the researcher. Secondary data is public or existing information which is collected and organized by others. Focus groups, personal investigation, telephone calls, and questionnaires are tools that researchers can use to collect data directly. Using any of these tools will lead to new information collected and organized by the researcher themselves. So they are all sources of primary data.

However, if we look at statement (E), research journals and newspapers contain data which has been collected and organized by others. This means that these will both be sources of secondary data. Research journals and newspapers are therefore not a source of primary data.
