What are secondary sources defined as?

Secondary sources are defined as information that is derived from primary sources or created by someone who did not experience the events or findings firsthand. This involves the analysis, interpretation, or summary of primary data. For instance, a book analyzing a historical event, a documentary based on interviews and primary sources, or articles that review various research studies all fall under the category of secondary sources.

The other choices highlight different concepts. The first choice refers to primary sources, where the information originates directly from the author or their firsthand experiences. The second choice also pertains to primary sources, as it describes firsthand accounts. The final choice suggests a form of report that relies solely on primary sources without interpretation or analysis, which does not fit the definition of secondary sources. Therefore, the correct option encapsulates the essence of secondary sources as information that is created from the interpretation of original data provided by others.
