Comparing Primary and secondary sources

Primary sources are more reliable than secondary sources as primary sources are originally created or written by you whereas secondary sources are written by someone else

is defined as factual, firsthand accounts of the study written by a person who was part of the study. The methods vary on how researchers run an experiment or study, but it typically follows the scientific method. One way you can think of primary research is that it is typically original research.

Secondary research is defined as an analysis and interpretation of primary research. The method of writing secondary research is to collect primary research that is relevant to a writing topic and interpret what the primary research found. It is less factual it is more of different information/opinions merged together
