Definition
Primary data are those that are collected for the first time. Secondary data refer to those data that have already been collected by some other person.
Originality
These are original because these are collected by the investigator for the first time. These are not original because someone else has collected these for his own purpose.
Nature of Data
These are in the form of raw materials. These are in the finished form.
Reliability and Suitability
These are more reliable and suitable for the enquiry because these are collected for a particular purpose. These are less reliable and less suitable as someone else has collected the data which may not perfectly match our purpose.
Time and Money
Collecting primary data is quite expensive both in the terms of time and money. Secondary data requires less time and money; hence it is economical.
Precaution and Editing
No particular precaution or editing is required while using the primary data as these were collected with a definite purpose. Both precaution and editing are essential as secondary data were collected by someone else for his own purpose.
