Question 1. What are primary and secondary data? Differentiate them?
Answer: Primary data is information collected by an investigator directly for a specific purpose, following a definite plan. Secondary data, on the other hand, is information that has already been collected by someone else and is available from published or unpublished sources. Primary data offers fresh insights, while secondary data provides a quick overview.
| Primary Data | Secondary Data |
|---|---|
| 1. Primary data are original and serve as raw material for statistical methods. | 1. Secondary data are like a finished product because they have already undergone statistical treatment. |
| 2. These data are collected by the investigator personally. | 2. Secondary data were collected and published earlier by someone else. |
| 3. These data are collected freshly according to an independent plan. | 3. These data already exist and can be found in reports, records, etc. |
🎯 Exam Tip: Remember that primary data is original and often more reliable, while secondary data saves time but might not perfectly fit your specific needs.
Question 2. Name the different methods of collecting primary data.
Answer: Primary data can be collected using several methods to ensure accuracy and relevance. These methods allow investigators to gather firsthand information.
1. Direct personal investigation
2. Indirect investigation
