Secondary research uses existing resources like company records, surveys, research studies and books. It is normally less time consuming than primary research, and can be less expensive.
Ginagamit ng secondary research ang impormasyon na makukuha, tulad ng mga rekord ng kompanya, mga survey, research studies, at mga libro. Kadalasan ay hindi ito kasing tagal ng primary research, at maaaring mas maliit ang gastos para dito.
