Principle Difference between Primary and Secondary Data
- Difference in Objective: The primary data collected by the investigator is always for the specific objective. Therefore, there is no need to make any adjustments for the purpose of the study. However, the secondary data collected by the investigator has already been collected by someone else for some other purpose. Therefore, the investigator has to make necessary adjustments to the data to suit the main objective of the present study.
- Difference in Originality: As the primary data is collected from the beginning from the source of origin, the data is original. However, the secondary data is already present somewhere and hence is not original.
- Difference in Cost of Collection: The cost of collecting primary data is higher than the cost of collecting secondary data in terms of time, effort and money. It is because the data is being collected for the first time from the source of origin. However, the cost of collecting secondary data is less as the data is gathered from published or unpublished sources.
