Answer
- Certain precautions as mentioned below should be taken while using secondary data :
- Before using secondary data. One should verify the level of reliability of the data.
- Data collected and published by government.
- semi- government or autonomous organisations are more reliable.
- The data collected by private organisations are less reliable because they collect the data to suit their own ideology or they might have some
- bias or prejudice present.
- The purpose of collecting data should be properly examined before it is used as secondary data.
- The method of inquiry used in collecting data should be known. From the knowledge of method applied. one becomes familiar with its limitations also.
- The time duration when the data was collected should be known because the data collected in remote past becomes irrelevant in the present circumstances.
- Before using secondary data, matters pertaining to scope of data. Region for which the data are collected. definitions of terms used and the selection of units should be ascertained.
- The limitation and drawbacks of the data should be known for the secondary data to be used.
- If alternative data are available. the data should be compared and then only proper data should be used as secondary data.
