Solution

The information which is collected by the investigator himself with a definite objective in his mind is called as primary data whereas when the information is gathered from a source which already had the information stored, it is called as secondary data. It can be observed that the data in $$1,3,$$ and $$5$$ is secondary data and the data in $$2$$ and $$4$$ is primary data.
