Explanation

The aim of this question is to check students' understanding of different types of data. There are 2 types of data:

- Primary data is the collection of original or raw data which are generated from field research. In this case, only RFI and surveys from customers are considered as primary data.

- On the other hand, secondary data is public information that has been collected by others. It is typically free or inexpensive to obtain and can act as a strong foundation to any research project — provided you know where to find it and how to judge its worth and relevance. Examples of secondary data are government statistics, industry associations, trade publications, published market reports, etc.
