Answer 2

Data that has been collected in the past by someone else is known as secondary data.

• Statistical data is broadly divided into two categories:- Primary data and secondary data.

• Secondary data is collected in the past by some other person and is available in the form of internal records or publications.
• The secondary data has to be modified according to the requirements before using it.
